To feed or not to feed? The dilemma of interacting with birds and other wildlife

Researchers are discovering plenty of ecological impacts — positive and negative — when humans interfere with wild animals’ natural eating routines.

When she was about 8 years old, Judy Elson received a 500-piece jigsaw puzzle from her great-aunt that featured North American birds. Her relative had a passion for feeding backyard birds, and Elson has carried on the tradition for the past 30 years, in turn passing on her enjoyment and dedication to her own children. “They put together the same jigsaw puzzle I did as a child and started recognizing birds even before they knew they were interested in them,” she says. With 12 feeders in her garden in Cary, outside Raleigh, North Carolina, she observes about 50 birds per day from up to 22 different species. “I feed the birds to benefit them, but it also brings them in closer to where they are easier to see,” Elson says. “Most of my feeders are outside a bay window in my dining room where I can sit and watch the birds. That is so enjoyable and relaxing.”

“I feed the birds to benefit them, but it also brings them in closer to where they are easier to see,” Elson says.

Backyard bird feeding is one of the most common ways people engage with wildlife in many parts of the world. Estimates show that about half of households in the United States, the United Kingdom and Australia feed birds. In Great Britain, homeowners provide enough food to support approximately 196 million birds.

While people have always fed birds with kitchen scraps and homemade feeders, the practice has substantially changed since the 1950s with the increased commercial availability of diverse bird foods and feeders, making it easier to attract a greater number of bird species to backyard gardens year-round.

Researchers are just beginning to understand the ecological impacts, positive and negative, of this massive human intervention. From helping birds survive the winter to boosting bird populations and reproduction, feeding is reshaping bird communities and behaviors and even altering migratory patterns.

A 2019 study led by researchers from the British Trust of Ornithology found an increase in the diversity of birds visiting garden feeders in the past 40 years in Britain. The study, based on data recorded by citizen scientists for the Garden Bird Feeding Survey, shows that “approximately half of all birds using feeders belonged to just two species in the 1970s, but by the 2010s, the number of species making up the same proportion of the community had more than tripled.” For example, according to Kate Plummer, a research ecologist with the British Trust of Ornithology and a lead author of the study, just 10% of volunteers saw wood pigeons and goldfinches at feeders in the 1970s, but now these two species are common visitors in close to 90% of gardens. After significant declines between the mid 1970s to the mid 1980s, the goldfinch population has more than doubled between 1990 and 2015.

“We think it is the use of feeders that is in part driving these levels of increase,” says Plummer. “In the 1990s, bird food companies targeted goldfinches and started producing finer seeds, which made it easier for the birds to get what they needed in gardens.”

Eurasian Blackcap, by Steven Mlodinow

Bird food provided in British gardens has also affected the Eurasian blackcap, which has evolved a new migration strategy. For the past 60 years, blackcaps are more often choosing to spend the winters in Britain’s urban areas rather than migrating to the Mediterranean as they used to. A study concluded that milder winters combined with increased bird feeding have contributed to the change. “Feeding is causing species to adapt and evolve,” says Plummer, who also led this research.

It’s not just in Europe that birds are taking advantage of people’s feeding activities in their gardens. In 2017, Vancouver, Canada, residents elected the Anna’s hummingbird as their official city bird. Described by the city as “classy, urbane and stylish with the heart of a tiger,” the tiny bird now helps the city build awareness of birds in the urban environment.

Anna’s Hummingbird, by Steven Mlodinow

Yet, Vancouver’s favorite bird is a relative newcomer to the city. In the past 20 years, Annas hummingbirds have expanded their winter range northward by more than 700 kilometers (435 miles). A study based on long-term data from Project FeederWatch, a citizen science program in the United States and Canada led by the Cornell Lab of Ornithology and Bird Studies Canada, found that the hummingbirds are now able to survive farther north in colder locations in part because more people are providing nectar feeders and planting exotic flowers in their gardens that bloom in different seasons, including the winter.

“It was quite rare to find an Anna’s hummingbird in the winter north of the California border 20 years ago,” says David Bonter, avian ecologist at the Cornell Lab of Ornithology and one of the study authors. “Most of those birds can handle cold temperatures as long as they have something to eat, and more individuals are surviving winter in places where they could not have previously,” he adds. “What surprised everybody involved in the study is how quickly it happened.” 

“What surprised everybody involved in the study is how quickly it happened,” says Bonter. 

The impacts of human feeding extend beyond birds. For example, in Australia, flying foxes are increasingly living in urban areas because they can easily access food all year. People choose to plant native and exotic plants that flower in all seasons, which entices the bats to spend more time in those locations.

While feeding animals can in some cases lead to increased survival and breeding success, there can be negative consequences as well. For example, a 2019 study of the impacts of human feeding on a group of bottlenose dolphins in Western Australia found that, while other factors may have also played a role, both calf survival and female reproductive success were negatively affected by feeding.

Up for Debate

Backyard bird feeding is the subject of extensive debate. For example, what are the long-term ecological consequences of changing the migratory behavior of birds? “The amount of human food supplied every single day is gigantic, and that genuinely has had a massive effect on the overall environment and the population of birds,” says Darryl Jones, author of The Birds at My Table: Why We Feed Wild Birds and Why It Matters.

European Goldfinch, by Steve Percival

For example, in a 2018 article, scientists raised concerns about the risks associated with increased disease transmission. Garden feeders can indeed spread disease by bringing birds into contact with species they would not otherwise interact with. Risks can be higher if feeding stations are not cleaned on a regular basis, allowing food waste and droppings to accumulate. The number of greenfinches in the UK declined from a peak of about 4.3 million in 2006 to about 1.5 million individuals in 2016 after a disease outbreak that researchers hypothesized could be due to feeders. In the eastern U.S., bird feeders facilitated the transmission of an eye infection that decimated the house finch populations in the 1990s.

A paper exploring the impacts of wildlife feeding on migration and disease suggests that one of the benefits of migration is that it allows animals to leave habitats where parasites have accumulated and eliminates infected individuals that cannot survive the journey, and so can reduce parasite infection in populations. “Staying in one place increases exposure to infection,” says Richard Hall, an assistant professor at the Odum School of Ecology at the University of Georgia and co-author of the paper.

Feed Responsibly

According to Hall, the implications of bird feeding are also complex, and while feeders can facilitate the spread of diseases, they can in certain cases help improve bird condition.

“When you feed birds you aggregate them and that increases the transmission of parasites, but if you are feeding the right kinds of food it also means they can have a better immune function so even if they come in contact with another sick bird or parasite in the environment they may be better equipped to fight off an infection,” he says, “so there is a balance there.”

If done responsibly, many researchers say, feeding can help populations in need, especially in winter, and increase biodiversity conservation. “What we do as humans tends to have a negative impact on wildlife, and many of the species using garden feeders like goldfinches were negatively impacted by the intensification of agriculture. That’s why they were in decline, but now we are putting feeders and they are increasing,” says Plummer. “If we can compensate in some way for other negative effects we are having on some of these species, it feels like we are doing something beneficial.”

Backyard bird feeding also plays an important role in establishing personal connections with nature, with benefits to human health and well-being. “As we are more and more in big cities where nature is becoming rare and more difficult to encounter, bird feeding is a desperate search for some connection with nature. If you put a feeder in your garden, truly wild animals will come and visit you,” says Jones. “It is an extraordinary experience.” 

The direct observation of the natural world can also get people to be more supportive of conservation efforts. “There is value in that human interactions with backyard birds make people realize the birds are in trouble, and we need to make more efforts to conserve what’s left,” says Bonter. 

“There is value in that human interactions with backyard birds make people realize the birds are in trouble, and we need to make more efforts to conserve what’s left,” says Bonter. 

A 2019 study that surveyed participants of Project FeederWatch in the U.S. to understand the connection between people’s emotions and what they observed at bird feeders, found that most people who directly observed a problem at their feeders, such as the presence of a cat or sick birds, reported they would take action.

“There is a high percentage of people who do something in response to what they see,” says lead study author Ashley Dayer, an assistant professor of human dimensions in the department of Fish and Wildlife Conservation at Virginia Tech. “People are doing a lot more than just the feeding itself. They are managing the predators out there, they are cleaning the feeders, they are taking a lot of actions.”

In Australia bird feeding is strongly discouraged, even though the proportion of people feeding birds is the same as in the Northern Hemisphere. “People are strongly motivated to feed birds and care about them, but they are doing so in the complete absence of any information or advice and don’t know how to do it properly,” says Jones, who just published a book, Feeding the Birds at Your Table, to advise people how to feed birds responsibly. 

Backyard bird feeding can have benefits as long as it is done correctly, and a number of resources such as Project FeederWatch provide guidelines and steps people can take to create a safe feeding environment for birds, such as frequently cleaning feeders, spacing them far apart from each other to reduce exposure to disease, providing nutritionally appropriate foods, planting native species or recording data to allow scientists to better understand bird populations. With a recent study published in Science revealing that bird populations in the United States and Canada have fallen by 29 percent since 1970 — even species “once considered common and wide-spread” — people may become even more motivated to put out feeders to help birds, so making sure it’s done correctly will be important.

#BlackBirdersWeek
May 31 – June 5, 2020 Everywhere! Twitter, Instagram, Facebook!
Organized by @BlackAFinSTEM in response to what happened to black birder Christian Cooper. But it’s also in response to the murders of Ahmaud Arbery, Breyonna Taylor, George Floyd, and the countless others. Many of us work in the outdoors, in urban areas and wilderness. It could’ve easily been anyone of us. We want our peers to not only recognize our existence but our experiences being Black. The history books set a precedent for civil unrest in the face of injustice. We want it to be clear that we stand with the protesters fighting against police brutality even as we organize a protest specific to being #BlackinNature.

Live Guided Birding Tour at the Panama Canal
August 25 – September 30, online, Gamboa, Panama
We are Eco/birding guides in Panama and we have created an amazing online birding experience for people who cannot travel due to the pandemic. We have attached cameras to our powerful scopes and can transmit videos of birds in the rainforest LIVE to people around the world. As a way to continue doing what we love, we came up with an idea that we think is innovative and practical during this difficult time that will allow people from all over the world to experience the rainforest live from the safety of their home. We are lucky enough to be able to transmit live from the middle of the jungle with a strong internet signal in an area famous for birdwatching and wildlife viewing. We have created a live guided birdwatching tour right next to the Panama Canal that includes 2 hours of birdwatching in a world famous birding area followed by a 30 minute driving tour of Gamboa, an old American Canal Zone town that is home to the Smithsonian Tropical Research Institute.

Fall Migration Celebration
November 8, Augusta, MI
The W.K. Kellogg Bird Sanctuary was founded in 1927 and deeded over to Michigan State University in 1928, so we are celebrating more than 90 years! The Sanctuary is an important migration stopover for waterfowl and the best place to view Trumpeter Swans in Michigan’s lower peninsula. Join us from 1 to 4 pm and look for migrating waterfowl on Wintergreen Lake, meet our education raptors, make crafts to take home, create enrichment for the resident birds, and learn about how and why birds migrate. There will be a decoy exhibit by local, award-winning decoy carver Willy McDonald of The Duck Blind, who will also be helping the kids with their crafts! 

Black-Necked Crane Festival
November 11, Bhutan
The Black-necked Crane is the last discovered of 15 species of cranes in the world. This majestic bird is endemic to the Tibetan Plateau and migrates to lower altitudes, including several areas of Bhutan, in autumn. In Phobjikha Valley, one of the major habitats in Bhutan, the arrival of the cranes signals the end of the harvesting season. The Black-necked Crane festival was first initiated with the objective of linking conservation of the graceful birds to the improvement of livelihood of the community. Over the years, as the festival gained popularity among the community people, visitors from the nearby Dzongkhags (districts) and international visitors, it became an annual event to welcome the cranes and to celebrate the centuries’ old relationship between the cranes and people of Phobjikha. Among the events is the popular Black-necked Crane dance performed by school children in crane costumes. The local community also performs folk dances and mask dances. The Black-necked Cranes have a sacred identify in Bhutanese culture and often appear in folklore, dances, and historical texts. Since 1987, Royal Society for Protection of Nature has been working to protect and rebuild the population of the Black-necked Cranes. 

Bhutan Bird Festival
November 11 – November 13, Zhemgang Dzongkhag, Bhutan
Zhemgang Dzongkhag (District) will organize the three-day “Bhutan Bird Festival,” which coincides with the Birth Anniversary of the Fourth King of Bhutan in Tingtibi Town. The festival has eleven enthralling events split into pre-festival, main events, and post-festival programs.

Zhemgang district is a popular birding destination. With the district’s boundary intersecting with three protected areas–Royal Manas National Park, Jigme Singey Wangchuk National Park, and Phrumshengla National Park. The district harbors more than 500 species of birds.

White-bellied Herons are found in the Mangde Chu (river) and its tributaries. All four species of hornbills found in Bhutan–Rufous-neck Hornbill, Great Hornbill, Wreathed Hornbill and Pied Hornbill are sighted at different elevations. Beautiful Nuthatch is occasionally sighted in the upper regions of Zhemgang.

California Swan Festival
November 13 – November 15, Yuba City, CA
The festival honors the return of tens of thousands Tundra Swans to their winter home. In close-knit family groups, the swans make a spectacular show for bird watchers and photographers. This three-day event offers more than 35 guided tours by experts, exploring a wide range of waterfowl habitats and other natural assets of the beautiful Yuba-Sutter region. Field trips include Swan Sighting, Ag/Wildlife Educational Tours, Historic Tours, Nature Hikes, and trips to the region’s National Wildlife areas. Registration for field trips (at affordable rates) begins online in late August. Free Junior Naturalist program, led by Shady Creek Outdoor School naturalists. Children of all ages will enjoy hands-on learning. Activities include crafts, games, live animal presentations and much more. A vendor fair is held all day Saturday and Sunday in the Swan Central building. Parking and entry to the Swan Festival are FREE, as are a wide range of workshops and presentations on wildlife education, natural sciences, ecosystem management, and photography.

Earth to Birds: Take the Next Left

Scientists have long thought that avian migration is guided by the magnetic field, but how, exactly?  The search has led to three very different hypotheses.

By Sophie Fessl, Knowable Magazine

Every fall, the bar-tailed godwit takes to wing and flies nonstop from Alaska to New Zealand — a journey of 7,000-plus miles. Countless other birds head off too, bound for warmer spots before returning in the spring. How they do it without getting lost remains mysterious to this day.

Scientists are convinced birds must be using some type of biologically based magnetic compass, but they have yet to figure out how such a system would work. Now the field is heating up, and the latest research is pointing away from one long-standing theory and bolstering some intriguing alternatives.

Clues have been piling up for decades. Back in the 1960s, researchers discovered that European robins can somehow sense Earth’s magnetic field. In the decades since, scientists learned that robins and a variety of other bird species use the field, which is created by movement of iron in Earth’s core, as a navigational aid. The birds combine this guide with information deduced from the sun, the stars and geographical landmarks to complete their voyages.

But a vexing question that remains is what sort of biological receptor birds use to detect the magnetic field.

“Key experiments by a group in Germany definitively showed that a magnetic sense exists. Now, more than 50 years later, we still don’t really understand how it works,” says neuroscientist David Keays of the Research Institute of Molecular Pathology in Vienna.

Today, researchers are focusing on three possible ways that a magnetic sense could work. One idea involves a form of iron with magnetic properties, called magnetite, acting as a sort of compass within cells that rotates to align with the magnetic field. Another contender, known as the radical-pair mechanism, hinges on a chemical reaction in a bird’s eye that is influenced by Earth’s magnetic field. A third hypothesis suggests that as a bird moves through Earth’s magnetic field, small currents are generated in the creature’s inner ear.

In all three of these scenarios, signals are produced and passed on to the bird’s brain to be processed and translated into directions. Here’s a look at each of them.

Testing their metal

The magnetite idea has been studied the longest. Though it is biologically possible — certain kinds of swimming bacteria use the iron mineral to orient themselves — evidence in higher animals remains elusive, with scattered reports that are not always reproducible.

“The history of the magnetite literature in vertebrates is basically, ‘I find magnetite here,’ ‘I find magnetite here,’ ‘I find magnetite here,’ but it’s not getting much further than that yet,” says biologist Henrik Mouritsen, who investigates magnetoreception in European robins and blackcaps and coauthored a 2016 overview of the topic in the Annual Review of Biophysics.

Mouritsen, of the University of Oldenburg in Germany, would like to test the magnetite hypothesis using a classic tool of biologists: Remove something from the animal and see what happens to its behavior. If magnetite is critical for navigation, destroying the magnetite-containing cells would affect the birds’ ability to find their way. But for this research strategy to work, scientists need to know just where to find magnetite in the robins. And even if they find it, “it’s a long way from showing a cell contains iron to showing it’s magnetite connected to nerve tissue that has any biological relevance,” Mouritsen says.

One major knock against the magnetite theory is that a bird’s compass senses only the axis of the magnetic field and not its polarity, says chemist Peter Hore of the University of Oxford, a coauthor on the Annual Reviews paper. Unlike the compass needles used by people, which rely on the magnetic field’s polarity to point toward the magnetic North Pole, birds know which direction the nearest pole is but can’t distinguish between north and south. So when scientists invert the magnetic field in the lab, birds don’t sense a change and continue to head in the same direction.

But magnetite particles would respond to a flipped field by pointing in the opposite direction, just like a compass needle would. If birds were depending on magnetite, they would sense the change and turn around to head in the opposite direction.

The eyes have it?

The weight of evidence gathered by scientists tilts toward another idea known as the radical-pair hypothesis, Hore says. Mouritsen also favors this idea, which is based on a protein in birds’ eyes called cryptochrome. When light hits cryptochrome, reactions within the protein generate a pair of molecules, called a radical pair. The two molecules in the pair each have an odd number of electrons, leaving each with a single, unpaired electron. These two extra electrons can have spins that are in the same (or parallel) direction, or in the opposite (antiparallel) direction, and they can also flip between these two states.

According to the radical-pair hypothesis, Earth’s magnetic field influences how likely the spins are to be parallel or antiparallel. How those spins are then translated into a compass isn’t certain, but scientists suspect that in a biochemical reaction in the bird’s eye, the two spin states could lead to different amounts of chemical products being made. The products could then influence signals sent from the bird’s retina to its brain, making it aware of the magnetic field.

A mechanism based on radical pairs instead of magnetite could potentially allow birds to detect magnetic fields, Keays agrees. But because the radical-pair system depends on light hitting birds’ eyes, he thinks there is probably more than one mechanism at work. “It seems counterintuitive to have a light-dependent magnetic sensor when you are flying at night,” he says.

Or maybe the ears do

Keays is testing a long-forgotten hypothesis, first proposed in 1882, that as a bird flies through Earth’s magnetic field, tiny electric currents are generated in its ear. This would happen through electromagnetic induction, akin to how a magnet that moves through a coiled wire creates an electric current in the wire. Extremely sensitive receptors would pick up the small voltages induced in the bird’s inner ear and send signals to the brain.

Electromagnetic induction is thought to be plausible in sharks and skates, which can sense electric currents in seawater. That same electrosensory system could potentially function as a sort of biological wire in which currents could be induced, allowing the animals to sense Earth’s magnetic field.

To test whether induction could work in a land animal like birds, Keays built a simple, scaled model of a pigeon’s inner ear: a plastic tube filled with conductive fluid. When he put the model in a rotating magnetic field, sure enough, a small current was induced. Keays suspects the pigeon behavior of rapid head-turning to scan the environment during flight may also serve to boost the voltage in the birds’ ears. He has also discovered a very sensitive electroreceptor in the pigeon’s inner ear, which is exactly where it would be needed for induction to work.

Though scientists in the field are finding many new and intriguing pieces of evidence, the definitive test that will finally reveal how birds “feel” the magnetic field has yet to be devised, Hore says. “What we need is a killer experiment that would have the power to show, once and for all, whether it really is radical pairs and whether it really is cryptochrome. But it’s actually very hard to come up with something.”

Inaugural #BlackBirdersWeek Breaks Stereotypes About Birders

By Emily Benson / High Country News

Sheridan Alford’s love of bird-watching stems from a simple fact: “Anybody can do it.” Old or young, through expensive binoculars or with the naked eye (or ear), in a bucolic park or from a city window, anyone can connect to the avian world around them. Alford, a graduate student in natural resources at the University of Georgia, in Athens, Georgia, studies African American participation in bird-watching, trying to understand why some Black people engage in the activity and others don’t.

She’s also one of the co-founders of a social media push, #BlackBirdersWeek, which launched on May 31. The campaign was sparked by the viral video in which a white woman threatened a Black birder in New York’s Central Park, announcing that she was calling the police “to tell them there’s an African American man threatening my life.” 

“I think a lot of us identified with that scenario,” Alford said in a recent interview. In response, she and other members of a grassroots group, @BlackAFinSTEM, who work in science or related fields, decided to organize a week of social media prompts. They hope to boost visibility of Black nature enthusiasts, highlight the value of racial diversity and promote dialogue within the larger (and largely white) birding community.

May 31 – June 5th, 2020 is the inaugural Black Birders Week.

High Country News caught up with Alford the day before the launch, during a tumultuous weekend of nationwide protests over police violence against Black people. In Western cities, from Albuquerque, New Mexico, to Denver and Seattle, peaceful daytime protests provoked by the killing of George Floyd in Minneapolis gave way to overnight chaos, as police fired tear gas and rubber bullets into crowds, and buildings and cars were destroyed. Officials responded with curfews, emergency declarations and National Guard deployments. The organizers of Black Birders Week addressed the synchrony of their project and the civil unrest directly on Twitter: “We want it to be clear that we stand with the protestors fighting against police brutality even as we organize a protest specific to being #BlackinNature,” they wrote.

This conversation has been edited for length and clarity.


High Country News: Who should participate in Black Birders Week? Who is it for?

Sheridan Alford: It is for Black birders. But who can participate? Anybody and everybody, and we encourage everybody to participate! We love seeing the support. When you’re trying to fight for something that you believe in, sometimes you just want to know that someone else is in your corner, fighting that same fight with you.

We are not excluding anyone. … The whole purpose is to highlight and showcase Black birders, and anybody can do that.

“We want it to be clear that we stand with the protestors fighting against police brutality even as we organize a protest specific to being #BlackinNature.”

HCN: Why is the Black Birders Week initiative important at this moment?

SA: At this point, things are popping up in cities around the country that are either racially driven or stereotypically driven, prejudice, whichever word you would like to use. The climate is shifting to where a lot of the acts against people of color or Black people are being filmed, and they are available to the general public — a lot of people are now seeing what some people have experienced their entire lives.

But we think that it’s very important to highlight the work that people are actually doing and kind of drive that conversation to, yes, look at us, and please acknowledge the hardship we go through — but as you acknowledge those hardships, also look at what we’ve been doing in our research, or what we’ve been doing in our communities to better the climate as a whole. So I think this week kind of fell exactly where it needed to, as far as time frame.

HCN: It’s happening right at the same time as these nationwide protests.

SA: And there was no way we could’ve predicted that!

“When you’re trying to fight for something that you believe in, sometimes you just want to know that someone else is in your corner, fighting that same fight with you.”

HCN: Do you see the initiative and the protests as parallel? Or not?

SA: I see them in parallel. … As a Black person, I feel for my people, within the riots and the protests and all the things that are happening across the country. And I think it all just further affirms and identifies what it is to be a Black person in America.

People need a break from a lot of the hurt that they’re feeling. I know a lot of my counterparts are like, I’m not going to get on social media today, I’m going to take the day to myself. I think providing this uplifting and celebratory week will give people that break that they need to mentally gather themselves as a lot of these racially charged and very heated discussions are being had all across the country.

You need the heat, but you also need something to offset that sometimes. I feel like that’s what Birders Week will provide.

HCN: It seems like these are two different ways to respond to the same thing — systemic racism — two different ways to try to dismantle that.

SA: Right. Two sides of the same coin; really, the same side of the same coin. It’s just different ways of hitting it at different angles, and all of it can only help, at the end of the day.

HCN: It feels like this campaign is a celebration of the diversity within the birding community — is that right? 

SA: I would say celebration, as well as a safe space. Because not everything is peaches and roses, and there are dialogues that need to be had. … Hopefully, we’ll be able to touch on some of the issues that people are truly feeling in their hearts and kind of hash things out.

“I think providing this uplifting and celebratory week will give people that break that they need to mentally gather themselves…”

HCN: What do people need to hear?

SA: The biggest thing is just allowing peoples’ voices to be heard. A lot of times, someone will say that they’ve created a safe space or, they’ll say, like, ‘Oh, yeah, we want to hear what you have to say.’ But then when you actually step out and say it, it’s not received well, or it’s discounted or discarded. 

It’s really just about voices and accountability and understanding that everyone, especially Black people, are human beings, and we would like the same treatment as everyone else.

HCN: What do you hope people watching or participating in Black Birders Week will take away from it?

SA: I think that one of the biggest takeaways will be to kind of disprove or muddle the generic stereotype of what a birder or a bird-watcher is.

A lot of times on bird walks, the people on the walk will automatically look to the men in the group for answers. … So it’s always important to be like, actually, no, the woman said that, or actually, no, this Black person actually knows a lot about this bird; to just kind of change the narrative about what not only a Black birder is, but what a Black scientist is.

HCN: How’s the reception been so far?

SA: The reception has been amazing and astounding. We’re all just really grateful, and really appreciative, and glad that people are looking for it; it seems to be something that a lot of people didn’t know they needed.

The silence of the owls

No one knows exactly how the nocturnal hunters manage their whisper-soft flight, yet it is inspiring the design of quieter airplanes, fans and wind turbines.

By Dana Mackenzie, Knowable Magazine

Every owl fancier has a story of the first time they heard an owl — or, rather, didn’t hear one. It’s unforgettable to see an enormous bird, whose wingspan can reach more than six feet, slipping through the air without even a whisper.

Justin Jaworski’s first close encounter came at a flying exhibition at the Raptor Foundation near Cambridge, England. “They trained the owls to fly very close to the audience,” he says. “My first experience was of ducking to avoid a collision. I heard only a very slight swoosh after it passed.”

Laboratory measurements have shown that the slight swoosh made by a barn owl is below the threshold of human hearing until the owl is about three feet away — a feat of stealth that biologists and engineers are far from completely understanding. But researchers from both disciplines are working to solve the riddle of silent flight — some with the aim of designing quieter fans, turbine blades and airplane wings.

Such owl-inspired innovations can reduce noise by as much as 10 decibels, similar to the difference in noise between a passing truck and a passing car, Jaworski and Nigel Peake write in an overview in the 2020 Annual Review of Fluid Mechanics.

Go gentle

Jaworski, an engineer at Lehigh University in Pennsylvania, is hardly the first scientist to be captivated by the puzzle of silent owl flight. In 1934, Robert Rule Graham — a British pilot and bird connoisseur — called attention to three structures on owl wings that might account for the owls’ silence.

More than 80 years later, his “three traits paradigm,” as Christopher Clark calls it, is still cited in many papers on owl wings. “He clearly knew birds very well, and he was an aeronautical engineer,” says Clark, an ornithologist at the University of California, Riverside. “Science was different in the 1930s. In our age of specialization, you don’t get that combination.”

First, Graham pointed out an unusual structure called the “comb,” which literally looks like a comb projecting forward from the wing’s leading edge. Second, he noted that most of the owl wing is covered with a soft layer of velvety feathers. Finally, he observed that the feathers on the trailing edge of the wing form a ragged fringe.

Most researchers still agree that the comb, the velvet and the fringe combine in some way to reduce noise, but the owl may have more tricks up its sleeve. “When all is said and done, I think we’ll have a number of mechanisms, including Graham’s,” says Clark.

To explain how an owl suppresses noise, it would help to identify where the noise comes from in the first place. For an airplane coming in for a landing, a large part of the noise comes not from the engines but from the flow of air around the plane, especially the sound produced at the trailing edge of the wings. The turbulent air rushing past the exposed edges of the wings translates to the dull roar you hear as the plane flies overhead.

One way to reduce this noise would be to make the trailing edge of the wing less hard, more porous and more flexible. This may be the function of the owl wing’s ragged fringes. Jaworski and Peake have mathematically calculated how engineers might use such porosity and elasticity to reduce noise, and how to quantify that diminished din.

Those calculations are supported by wind-tunnel experiments: A variety of porous materials do dial down the noise. Work by Thomas Geyer at Brandenburg University of Technology in Germany has found that a poroelastic wing the size of an owl’s can be about 2 to 5 decibels quieter than a regular wing.

However, says Geyer, the right porous material is crucial; in the wind-tunnel tests, some materials actually increased high-frequency noise. Measurements of owls in flight show that their wings mute only frequencies higher than 1,600 hertz (on a piano, two-and-a-half octaves above middle C). Since this is roughly where the range of rodent hearing begins, it’s the range that an owl would benefit most from suppressing as it hunts for a meal.

Jaworski and Ian Clark (no relation to Christopher) of NASA’s Langley Research Center have attempted to mimic the owl’s velvet by covering a standard airfoil with various kinds of fabric. “The winning textile was a wedding veil,” says Jaworski. However, it may not be necessary to donate your nuptial accessories to science, because the researchers got even better results by attaching tiny plastic 3-D–printed “finlets” to the blades of a wind turbine.

“Over a certain frequency range, we saw a 10-decibel noise reduction,” Jaworski says. “That may not sound like much, but in air acoustics, engineers fight over two or three decibels. Ten decibels is half as noisy. That’s a massive change for any technology.” Siemens, a manufacturer of wind turbines, has apparently been listening, and recently unveiled its second-generation “Dino Tail” turbines that have combs directly inspired by the owl wing.

Feathery enigma

Though owl wings are providing new insights into noise reduction for aeronautical engineering, engineers have had less success describing the physics of owl flight. According to ornithologist Clark, the engineers may not even have identified the most important source of noise in owl aviation.

If you’re trying to build an owl, rather than a wind turbine or an airplane, you’ll notice several differences. Owls have feathers; airplanes don’t. Owls flap their wings; airplanes don’t. There’s a good reason that aeronautical engineers prefer stationary, solid wings to flapping, feathery ones: They are easier to understand.

But if you are a biologist, to ignore flapping is to ignore a fundamental ingredient in avian flight, says Clark. As bird wings flap they change shape, and as they change shape the feathers rub against each other, causing noise. This noise is frictional, not aerodynamic, produced by the contact of solid against solid.

As bird wings flap they change shape, and as they change shape the feathers rub against each other, causing noise.

Ian Clark, ornithologist

In Clark’s view, the purpose of the owl’s velvet and the fringes is to reduce frictional noise between the feathers while flapping. Clark concedes that his argument would be moot if owls glided while hunting, but video evidence shows they do not: They flap when taking off, they flap when landing and they even flap when “coursing” for prey.

And the fringes are not only on the trailing edge of the wing, where the aerodynamic theory would predict them to have the greatest noise-reducing benefit. Fringes also exist on the leading edges of the feathers, where they do not affect aerodynamic noise, as well on some feathers that are not even exposed to the airflow. This suggests that their purpose is not aerodynamic.

Clark says that we may be asking the question backward. Instead of asking why owls are so quiet, we should ask why other birds are so loud. The answer is feathers. “Feathers are amazing structures, and probably the reason birds are so successful,” Clark says. But they come with an evolutionary cost: “If you’re going to build a wing out of feathers, they are going to produce frictional sound.” To become silent hunters, owls evolved special adaptations that reduce this disadvantage.

Owls are not the only kind of bird that has solved this problem. Some species of Australian frogmouths have independently developed the same adaptations. These birds are also carnivorous and have wings that are soft and fluffy with combs and ragged fringes. In Graham’s day, people assumed that frogmouths were closely related to owls, but genomic analysis has proved that they are not. While less studied than owls, they too are silent flyers.

“Evolution often takes a quirky path,” Clark says. “One way you can home in on the underlying mechanical principles, and tell them apart from quirks, is with convergent evolution.” When two unrelated animals have the same adaptation, it suggests that the feature confers a benefit — in this case, stealth.

At present, there are two ways to understand owl flight: an engineering view informed by the equations of fluid motion and wind-tunnel experiments, and a biological view based on anatomy, behavior and genomics. A truly integrated story will probably require both. Even engineers realize that idealized studies based on rigid, unfeathered wings are not enough. It’s quite possible that the owl uses its feathers and small shape adjustments of the wing actively, rather than passively, to manipulate airflow. Engineers aren’t even close to understanding this process, which spans several size scales, from the barbs of the feathers to the individual feathers, to the entire wing.

“What is missing to us is the microscopic point of view,” says Roi Gurka of Coastal Carolina University in South Carolina, whose experiments with flying owls have led to beautiful computer simulations of the flow field around a flapping owl wing. “I understand the wing,” he says, but understanding the role individual feather morphology plays in noise reduction is another matter.

While the scientists debate, the barn owl will continue flying as it always has: its face as round and imperturbable as the moon, its ears trained on its next meal and its feathers treading gently on the air.

Taking Flight! Children’s Love of Birds Inspires Hope for the Amazon

Help CONAPAC and the Morpho Institute bring binoculars to student birders in the remote Amazon.

Guest post by Brian Landever, Director of CONAPAC, and Christa Dillabaugh, Director of the Morpho Institute

What happens when you mix more than 1000 students, 250 teachers, 75 binoculars, 26 remote Amazon rainforest communities, a host of international partners, and one ecolodge?  An incredible bird education project in the heart of the Peruvian Amazon! 

Thanks to collaboration between CONAPAC, the Morpho Institute, and the Cornell Lab of Ornithology, students from pre-school through high school are learning about behavior, habitat needs, and cultural significance of birds in the Amazon. Their passion became evident when students presented unsolicited skits, songs, and dances related to bird conservation during CONAPAC’s April 2019 visits to participating villages.

Then, in September 2019, 26 remote communities participated in this region’s first ever bird festival. Hosted in the community of Manati on the Amazon River, students inspired onlookers with bird-related art, music, and dance. Read all about this birding festival and CONAPAC’s educational efforts in the Amazon in our previous post: A Bird Celebration REVOLUTION is Happening Right Now in the Amazon.

With growing publicity, the students and teachers are excited to be recognized as leaders in a new force for conservation of the Amazon rainforest.

The Morpho Institute is proud to support this growing movement via our Amazon Binocular Project. When children hold up a pair of binoculars and focus on a familiar bird for the first time, their faces light up with glee. When binoculars are left in their communities, students become experts on the behaviors and habitats of their local birds. But we don’t yet have enough binoculars to meet demand. The 75 pairs of binoculars that we have provided are in constant use, and we aim to add 225 more by 2021.

A Bird Celebration REVOLUTION is Happening Right Now in the Amazon

Fostering a love of birds through education in the Amazon, CONAPAC is increasing environmental awareness and jump-starting a birding revolution in Peru.

By Brian Landever

More than 1000 students from 26 remote Amazon rainforest communities gathered this September to participate in the first-ever bird festivals in the Peruvian department of Loreto. They awoke early, traveled to neighboring communities along the Amazon rivers, and spent the days presenting elaborate performances related to bird conservation and discussing the impact of birding in their communities.

Activities celebrating birds and birding have gained momentum since 2017, and a revolution is building. It’s a celebrative kind, raising spirits and enhancing the cultural arts.  Children are showing excitement for the natural world, and their parents are following suit.  It’s in good time; Peru has been listed as the world’s best country for bird watching, and is second worldwide for most species of birds registered. Most importantly, these activities are showing concrete increases in bird conservation.

The people in this region are strong, accustomed to the intense Amazon sun, and mainly fish and grow crops for sustenance. Children and adults cheerfully play sports every afternoon, and couples help one another with fishing. Their music with flutes, drums, and rattles, their regional dances related to animals, and their stories about the meanings behind bird encounters are just a few aspects of the people’s rich culture. Their homes may not have electricity or running water, and are over 100 kilometers from the closest city, but the warmth and comfort they have amongst one another in communities makes international visitors appreciate coming here.

Although many visitors return frequently, until recently, the forest was not commonly explored for leisure; entering only when hunting was the priority. That’s all changing now. Now, there’s a greater awareness of how the birds are important to the environment, developing the people’s pride for their home.

Education is key

Thousands of K-12 students became involved in this movement over the past several years. Their teachers are leading outdoor, project-based classes to inform them of the region’s bird species’ habitat, behavior, nesting, diet, cultural stories, and more. And their new curriculum is paying off.

During these festivals, students share what they are learning in unique ways. Some students perform activist theatre, portraying stories of birds fighting to retake their habitat after being encroached upon. Other students draw finely detailed portraits of the birds with masterful skill, and still others have crafted replica bird nests to explore nest functions. One high school senior rapped about birds’ beauty and the tragedy of losing them. Another 14-year-old young woman’s dramatic poetry about respecting birds in nature left watchers teary-eyed. Groups of younger students were happy to be included too, sharing well-practiced songs about birds’ beauty. One mother even rose to share an unsolicited folk song about the Blue-gray Tanager.

The impact of this is visible. Children are heard stopping their classmates from killing birds, and their parents report no longer hunting birds in unsustainable ways.  

Behind these activities are 250 dedicated teachers, Peruvian NGO CONAPAC, led by Brian Landever, and the Cornell Lab of Ornithology (CLO), represented by Karen A. Purcell and Marilu López Fretts. They have been co-creating training workshops each year since 2017, resulting in dozens of dynamic lesson plans, materials, communication methods, and culturally embedded evaluations all focused on keeping enthusiasm strong.

Building a revolution

In 2017, the first ornithology training workshop was held for teachers from these rural communities. Karen A. Purcell and the “Celebrate Birds” citizen science team began co-developing materials, and soon launched an engaging, fun, culturally sensitive educational program focused on bird conservation.

In 2018, teachers began notably increasing their involvement following bi-monthly meetings with the CLO team. The large WhatsApp group began to receive hundreds of photos posted weekly by the teachers, excited to share their progress, in turn motivating one another.

In early 2019, there was no doubt that the program had matured when students presented unsolicited, elaborate skits and dances related to bird conservation during CONAPAC’s visits to their communities. Thousands of photos of class developments began to fill the WhatsApp group monthly, and the program supporters, JBQ Charitable Foundation and the Amazon Binocular Project, have stated they could not have used their donations in a better manner.

When the last workshop was held in June 2019, at Explorama’s lodges, located on the Amazon and Napo rivers, the teachers themselves opened the event. They had prepared creative songs, photo-realistic sketches of birds, and enthusiastic presentations of what they had accomplished to date with their students. The entire week was festive, productive, and further prepared the teachers with strong class curriculum. CONAPAC’s footage of these classes on its YouTube channel effectively capture the enthusiasm of these events.

In turn, the students are receiving motivated class sessions and can see that they have become part of something that is expanding, and being appreciated worldwide. The culmination of this, five bird festivals that took place in September, has surpassed everyone’s expectations.

Moving forward

During these festivals, the perspectives of local people were inquired into more closely in open conversations following each morning’s presentations. Discussions amongst parents, community authorities, students, and teachers with CLO are building an understanding of the movement’s impact on people’s lives and environment.

New, exciting initiatives were also shared during the festivals, including long trails, or “senderos,” complete with benches and gazebos, built by parents for children to birdwatch in the forest, building their understanding of how birds live in nature.

Right now, thorough, co-created program evaluations are being led by CLO to analyze the progress being made. The classes continue regularly, and bird clubs are meeting regularly amongst the most interested students from each community. Eight birdwatching trails have been developed, and more are being planned. The first community-led bird festival in Loreto was held on October 30th, 2019, uniting 11 communities and 600 people, leading to a press report.

The potential for this program to have a positive environmental and social impact is clear. As it gains more attention in Peru and internationally, it will add momentum to the global movement to respect and conserve the Amazon rainforest. For bird appreciators, incorporating ongoing citizen science data from students and community members will expand the database of birds from this region on Cornell’s eBird.com. If the Peruvian board of education replicates the training and materials in other areas of Peru, the impact would multiply tremendously, further fueling the country’s strong efforts to be a prime tourist destination. If more bird festivals occur, celebrating birds could become a proud new tradition.

Nonetheless, what has happened over the past three years has given unforgettable, enjoyable memories to thousands of children in Peru, empowering them with activities that contribute to the wellness of the Amazon rainforest and the planet overall.

Brian Landever is Director of Conapac, devoted to conservation and community development, in Iquitos, Peru.

Winners of the Birds of South America Photo Contest

From this July to the end of September, birdseye.photo was flooded with hundreds of beautiful photos of birds endemic to South America for our summer photo contest. We got dozens of parrots, tanagers, gulls, owls, ducks, woodpeckers, hummingbirds, hawks, herons, and so many more! It was extremely difficult to pick just three winners, but here we are.

The BirdsEye team collected our ten favorite photos, then consulted professional photographers to choose the final three.

Here, along with a short story about each photo, are the winners.

FIRST PLACE
Debbie Reynolds, Sunbittern

Debbie’s story: “I love “shooting” birds, and just happened to be going to the Pantanal in September, saw your email asking for shots of South American Birds, and thought I would send you a few of my favorites. 

 “This photo was taken on the Cuiabá River, where we stayed at the end of the Transpantaneira Highway at the Hotel Pantanal Norte.  We were riding in an 8 person boat up and down the river, looking for birds and mammals, and spotted this Sunbittern on a sandbar, just getting ready to take off.  

“The boat was bouncing around, but I managed to lock my camera onto the bird before it took off, and it happened to fly right in front of the boat.  I was using my Canon EOS 5D Mark IV camera, with a 400 MM lens.  F/5.6 and ISO 640.”

SECOND PLACE
Alexandre Gualhanone, Yellow-fronted Woodpecker

Bonnie’s story: “I was able to witness these gorgeous Hyacinth Macaws at Porto Joffre in the central portion of the Mato Grosso, Pantanal, Brazil. I was with a photo group that was there for birding and Jaguars. We took a tour around the property for birds before we were to go out in boats to see the wildlife on the rivers and channels in the area.

“As we were coming to the end of our tour we saw this pair of Macaws playing at the top of a palm tree. They played for a very long time and I and my group were able to take many photos. We were also lucky to get the Ipy trees in the background as they only bloom their pink blossoms for 5 days out of the year and the contrast of the blue macaws and the pink in the background made the photos.

“I used a Nikon 7100 with an 80-400mm lens, at 1/800 and f6.3.”

Congrats to our winners, and thank you to everyone who participated! – The BirdsEye Team

Note: Special winners, who were among the first 25 to submit quality photos of species on our “need these birds” list, will be announced soon!

Luke Tiller has his eye on raptors

October Birder of the Month
By Amanda Grennell

Hawk expert Luke Tiller.

For Luke Tiller, lifelong outdoor enthusiast, self-taught hawk expert and tour guide, and environmental consultant, watching birds is all about their behavior.

“I like leading tours where it’s not just chasing some rare bird, but there’s some kind of spectacle,” said Luke. “I want to see something amazing that kind of knocks your socks off.”

Like many birders, Luke took a circuitous path to birding. After growing up in London and earning a degree in Philosophy, Luke found his way through various nonprofits to a management and marketing job with Connecticut Audubon. That’s how Luke discovered his love for raptors – which he describes as an “acceptable gateway” to birding.

“They’re big, they’re voracious. If you have a bald eagle flying over your head it seems to have more of an immediate impact on people,” said Luke.

When he got sick of working in offices, Luke found a way to make a living outdoors by running hawk watches on the East Coast and the Great Lakes, running the “Soaring Bird Surveys” in Israel, and guiding tours on major raptor migration routes. According to Luke there’s no magic or secret to becoming an expert in raptors – it’s comes just from watching them for a long time. After more than 15 years of focusing on raptors, Luke has definitely earned his expertise.

Unlike songbirds, raptors migrate during the day – so you can actually watch migration happening in real time. In the Americas, birds like the Swainson’s Hawk, the Broad-winged Hawk, and the Turkey Vulture migrate from the Northern continent to Central and South America in the fall (August to October), and back again in the spring (March to May). A similar migration pattern happens from Europe and Asia to Africa, for other raptor species.

Because raptors don’t usually migrate over the ocean, the land’s geography forces them to funnel through chokepoints – leading to a phenomenal number of birds in the sky.

“I’ve been in Panama when we’ve had had one million birds migrate in one day,” said Luke. “The sky gets blackened with birds.”

And what exactly keeps these powerful birds away from the water? The absence of thermals to keep them aloft. Instead of wasting energy on flapping, most raptors spend their time simply gliding from one thermal to the next. Flying distances of up to 7,000 miles, which the Swainson’s Hawk accomplishes every year, they need to be as efficient as possible. But above the massive heat sink that is the ocean, thermals don’t usually form.

In fact, Luke points out, seabirds can be quite dangerous for a raptor that ventures too far from shore. To cross between North Africa and Spain, raptors will get as high as they can above land and then coast over the Straight of Gibraltar. But sometimes they don’t make it.

“They are a fish out of water on the ocean. Gulls will force them out of the air and down to the water and drown them and eat them. And gulls don’t have talons like raptors, so they just rip them apart. It’s kind of gross.”

Some raptors, like Peregrine Falcons and Ospreys, are more adapted to life on the water, and consequently are built for lots of flapping, rather than gliding.

Apart from these natural chokepoints, raptors congregate in other places as well. The Amur Falcon, Luke says, migrate from Siberia and Korea to South Africa along the Doyang river. Before making the 3,000 mile journey over the Arabian Sea, they stop at a hydroelectric dam in Nagaland, a northeastern state in India, hundreds of thousands of birds at a time. Luke was lucky enough to guide the first commercial tour to see this gathering.

The tour was motivated by a remarkable story: with fishing stock decimated by the dam, the local people turned to the Amur Falcons as a food source, repurposing fishing nets to catch the birds. During the huge migration event, they were caught by the thousands, and within a couple years the decline in population was noticed at their wintering grounds. But when Bano Haralu, a local journalist and conservationist, uncovered the source of the population decline, multiple organizations stepped in to protect the birds. They explained the problem to the villagers subsisting on the falcons, who then decided to stop hunting the birds and invest in tourism instead.

As a keystone species, the Amur Falcons’ story is not just about the birds, it’s about the ecosystems that depend on them. With the help of the government, forest service, NGOs and local communities, zero Amur Falcons are captured or killed in northeast India now – a resounding success for the environment.

Luke is fond of many environmental success stories with raptors, citing it as another reason to enjoy hawk watching. Bald Eagles, for example, were down to 500 breeding pairs in the 1960s. But after reducing the use of DDT, their numbers have soared past ten thousand pairs. Reduction of pesticides, along with a captive-bred release program also allowed Peregrine Falcons to recover.

“When you are talking about the environment many stories are depressing. I think it is important to share stories of success, especially when the problems are usually manmade,” said Luke.

Though he’s reluctant to pick a favorite – “Favorite birds are whatever you can think of when you get asked that question, and they change often,” – Luke said his current favorite is the Harpy Eagle.

The national bird of Panama, the Harpy Eagle is endemic to South and Central America, living in pristine forest habitat. Because of this, they can be somewhat hard to find. Luke puts a sighting between uncommon and rare. But, if you know the location of a Harpy nest, chances are good, as their chicks stay around for up to a year. Luke had the great fortune to travel to a Harpy nest in Panama a couple years ago.

“We had an hour drive, a two hour boat ride, about an hour and a half hike through the jungle where it was 90 degrees and 100 percent humidity. But it was all worth it when we finally got to the nest. Here was this baby Harpy and the mother sitting together. It was pretty amazing,” said Luke. “That’s why I like hawk watching and migration. You go to interesting places and you see this incredible spectacle.”

August Birder of the Month: Rene Valdes

Birding and Conservation in Mexico with Rene Valdes
By Amanda Grennell

One thousand. That’s how many birds in Mexico Rene Valdes aims to identify before he turns forty. He’s got two more years and only 31 species to go — and after learning that Rene basically lives and breathes birding, we won’t be surprised when he hits his goal.

How did Rene get into birding? In high school he volunteered to develop nature trails in an estuary preserve in Mazatlán. The lead on the project, a birder from the Netherlands, lent Rene his binoculars and challenged him to find “Woody Woodpecker” out on the estuary. That first bird, actually a
Pale-billed Woodpecker, got Rene hooked — soon he was identifying all the birds in his hometown, and a little later began photographing birds. Little did he know that there are about 1,100 bird species native to Mexico.

In college, Rene chose to study biology, but specialized in ornithology by joining in research projects, sometimes at other universities, to study birds and conservation. At one point he put his formal studies on pause to spend four months in Peru, studying parrots in the Amazon. That experience led him to research parrot conservation in Northeast Mexico for ten years after graduating college.

During this time, Rene focused on the Maroon-fronted Parrot, an endemic species to Mexico that is endangered. While living and studying in Northeast Mexico, Rene started guiding in his free time. He just couldn’t get enough of birds. He started leading tours in Mazatlán and the Pacific Coast, but branched out to new spots he learned about from his personal birding trips — Chiapas, the Yucatan Peninsula, and Monterrey, where Rene now lives. “Chiapas is one of my favorite places,” Rene said.

In 2011 Rene stopped doing academic research, switching to consulting with private companies. But he’s always watching birds, and studying their behavior for fun. “Last year I was studying a nesting colony of terns and gulls,” Rene said. Now he works with wind farm companies to do bird surveys on the Yucatan Peninsula to better understand how building windmills will affect bird populations. His studies aim to minimize the effects of wind farms on birds.

For the past six years, Rene has also guided tours for the Rio Grande Valley Birding Festival, which focuses on birds living along the border. It’s a huge affair with almost 100 guides — well worth checking out if you want to add more than 30 new birds to your life list. (This year’s festival is Nov 6-10, so there’s still time to plan a trip!)

Disclaimer: Rene also works for BirdsEye, developing content, uploading new content, approving photos on birdseye.photo, and coordinating citizen science projects. He’s worked on creating Birds of Ecuador, Birds of Peru, and Birds of New Guinea — some of our apps that streamline guidebooks into excellent smartphone apps. And he reviews eBird sightings for three states in Mexico.

Like many birders, Rene is also a photographer. I might be biased, but Rene’s photos are stunning. But he’s never had lessons or taken any classes. So how did he hone his skills? “It was just practice.” Rene said. “I made a lot of mistakes. I started with a film camera, so I learned from my mistakes and tried to fix them.” Rene did get help from a friend to jumpstart his editing skills in photoshop, but after that he says he learned by himself, again, through lots of practice.

You can view many of Rene’s best photos on his birdseye.photo page.

Rene’s favorite bird may not be what you expect. In a country filled with vibrant birds in a rainbow of colors, Rene’s pick is a simple black and white: the Tufted Jay. “Very endangered species, but it is beautiful. There are no more than 1,000 birds left in the wild. It is gorgeous,” Rene said. Rene’s favorite tours are to the Mexican states of Sinaloa and Durango, where groups of up to twenty Tufted Jays can be seen.

Rene is also partial to the Horned Guan because of the effort required to find its territory. You have to hike 5-6 hours to the top of a cloud forest in Chiapas to reach one of the only places it is known to live.

It’s hard for Rene to pin down exactly why he loves birding. “It’s addictive actually,” Rene said. “I travel a lot in Mexico to find birds that I have never seen before.” His Mexico list sits at 969 bird species identified, though Rene says he’s only snapped photos of about 600-700 different species from Mexico. “Discovering a new bird that is awesome, colorful, just beautiful birds. That helps people get into birding,” Rene added.

“As I say to my friends, when you have very few birds left, it is very expensive to get them. You have to travel a lot for only one bird sometimes. The first 200 or 300 species are for free.” 

Even still, Rene saw five new birds on a recent trip off-shore of Baja. Yep, he’s going to have no problem getting to 1,000. Go Rene!

Rene loves birds, and they love him. Photo: Rene Valdes
