A new study from University of Utah researchers suggests that, due to deforestation and habitat degradation, more bird species may be endangered that previously thought – including species that may not have been discovered yet.
By combining wind speed data with the measured accelerations of a golden eagle outfitted with GPS tracking instruments, researchers suggest that, rather than hindering flight, turbulence is a source of energy that birds may use to their advantage.
Building lights are a deadly lure for the billions of birds that migrate at night, disrupting their natural navigation cues and leading to deadly collisions. But even if you can’t turn out all the lights in a building, darkening even some windows at night during bird migration periods could be a major lifesaver for birds.
As Australia officially enters winter, UniSA ecologists are urging coastal communities to embrace all that the season brings, including the sometimes-unwelcome deposits of brown seaweed that can accumulate on the southern shores.
Researchers set out to learn how extreme winter cold and heat affected 41 common bird species in eastern North America. They found that individual bird species respond differently to these weather events, and extreme winter heat may lead to longer-term changes in bird populations.
Art Garfunkel once described his legendary musical chemistry with Paul Simon, "We meet somewhere in the air through the vocal cords ... ." But a new study of duetting songbirds from Ecuador, the plain-tail wren (Pheugopedius euophrys), has offered another tune explaining the mysterious connection between successful performing duos.
Many seabirds in the Northern Hemisphere are struggling to breed — and in the Southern Hemisphere, they may not be far behind. These are the conclusions of a study, published May 28 in Science, analyzing more than 50 years of breeding records for 67 seabird species worldwide.
Karina Sanchez, a Biological Education Ph.D. candidate at the University of Northern Colorado, has been awarded a $20,000 American Dissertation Fellowship award from the American Association of University Women (AAUW), an organization that promotes education and equity for women and girls. Her dissertation involves researching how noise and light pollution and landscape composition in urban settings affects American robins, specifically their bird song.
Each of the 13 students in URI Assistant Professor Justin Richard’s class is assigned a chicken and is instructed to train it to do several required behaviors, as well as other behaviors the students choose themselves. All train the birds to understand that when they hear a clicker, a food reward will be delivered. They also train the birds to peck at a target. Some students are also training their chickens to get on a scale to be weighed, identify a particular color, or jump through a hoop.
With its tree-laden campus and adjacent protected natural reserves, UCI enjoys being home to a great variety of bird species. One particular raptor continues to capture the attention of the many avid birders in Orange County: the white-tailed kite. This iconic bird of Orange County – named for its ability to hover in the air while hunting –nearly went extinct throughout California in the early 1900s due to human-related threats.
Biologists have identified specific neural firing patterns that can induce stuttering and stammering in songbirds. The discovery offers a model system that could enable researchers to uncover the origins of speech dysfunction in humans, and possible treatment to restore normal speech.
Scientists from around the world have produced a new analysis—believed to be the most detailed study of specialized ecological data from global forests—that is furthering science’s understanding of species interactions and how diversity contributes to the preservation of ecosystem health.
House finches are locked in a deadly cycle of immunity and new strains of bacterial infection in battling an eye disease that halved their population when it first emerged 25 years ago, according to new research from the Cornell Lab of Ornithology.
It’s a common sight: pelicans gliding along the waves, right by the shore. These birds make this kind of surfing look effortless, but actually the physics involved that give them a big boost are not simple. Researchers at the University of California San Diego have recently developed a theoretical model that describes how the ocean, the wind and the birds in flight interact in a recent paper in Movement Ecology.
Biologists set out to compare four main lists of bird species worldwide to find out how the lists differ—and why. They found that although the lists agree on most birds, disagreements in Southeast Asia and the Southern Ocean could mean that some species are missed by conservation ecologists.
For the past 50 years, the U.S. Fish and Wildlife Service (USFWS) has been assembling counts of bald eagle nests to track the triumphant recovery of America’s national symbol. But in its new bald eagle population report – tabulated with the help of results using eBird data from the Cornell Lab of Ornithology – the USFWS found many more eagles than previously thought to exist in the Lower 48 states.
As gatherings to observe whooping cranes join the ranks of online-only events this year, a new study offers insight into how the endangered bird is faring on a landscape increasingly dotted with wind turbines.
Monte Neate-Clegg and colleagues tracked the demographics of 21 bird species over 30 years of observations from a mountain forest in Tanzania. For at least six of the species, their population declined over 30 years could be most attributable to rising temperatures – an effect of a warming world. Smaller birds, as well as those that live at the lower part of their elevation range, were at higher risk for slowed population growth.
Keeping backyard chickens was already on the rise, and the hobby has become even more popular during the COVID-19 pandemic. Now, a University of Georgia researcher cautions that the practice has risks not just for chickens, but for wildlife and people as well.
Famous for their uncanny ability to imitate other birds and even mechanical devices, researchers find that Australia’s Superb Lyrebird also uses that skill in a totally unexpected way. Lyrebirds imitate the panicked alarm calls of a mixed-species flock of birds while males are courting and even while mating with a female.
A new study in the journal Diversity by researchers from Paul Smith’s College Adirondack Watershed Institute (AWI) and Wildlife Conservation Society (WCS) finds that bird communities in two rapidly developing rural landscapes react differently to increased “rural sprawl.”
The COVID-19 pandemic has changed human behavior, and that has major consequences for data-gathering citizen-science projects such as eBird, run by the Cornell Lab of Ornithology. Newly published research finds that when human behaviors change, so do the data.
A new study by Cornell Lab of Ornithology scientists aims to clarify the status of the non-native European House Sparrow, using 21 years of citizen science data from the Cornell Lab’s Project FeederWatch.
Love them or hate them, there’s no doubt the European Starling is a wildly successful bird. A new study from the Cornell Lab of Ornithology examines this non-native species from the inside out to learn what exactly happened at the genetic level as the starling population exploded and spread all across North America?
A new study shows how climate change is having a much greater impact on birds than small mammals in the Mojave Desert in the southwestern United States. The study could inform conservation practices and shed new light on how climate change affects various species differently. The research drew on cutting-edge computer modeling as well as survey data from more than 100 years ago.
The 24th annual Great Backyard Bird Count (GBBC) is a great opportunity for all budding birdwatchers and bird-count veterans to use their skills. People from around the world count the birds they see for at least 15 minutes on one or more days of the count, and then enter their checklists online. The GBBC takes place February 12 through 15.
Foraging humans find food, reproduce, share parenting, and even organise their social groups in similar ways as surrounding mammal and bird species, depending on where they live in the world, new research has found.
A new study from scientists at the Cornell Lab of Ornithology examines public attitudes toward non-native bird species and whether people are willing to manage them to protect native cavity-nesting birds, such as Eastern Bluebirds and the American Kestrel. The findings are published in the Journal of Environmental Management.
Scientists from the Cornell Lab of Ornithology and Colorado State University used observations from the Lab’s eBird citizen-science program to estimate the seasonal species richness of nocturnally migrating passerines within 333 well surveyed urban areas in the contiguous U.S. “Richness” is defined as the number of different species in an area.
There's been a huge bump in the number of people connecting with birds and nature as people stuck close to home during this past year, and the trend is continuing. The perfect gift for new—and veteran—birdwatchers is the gift of knowledge. There's so much to learn about birds! Below are holiday gift ideas that are meaningful and environmentally friendly—and your purchase supports the nonprofit conservation work at the Cornell Lab of Ornithology.
U.S. pollution regulations meant to protect humans from dirty air are also saving birds. So concludes a new continentwide study published today in The Proceedings of the National Academy of Sciences. Study authors found that improved air quality under a federal program to reduce ozone pollution may have averted the loss of 1.5 billion birds during the past 40 years.
Biodiversity Research Institute announced that a series of scientific studies that assessed the impact of mercury on air, water, fish, and wildlife in New York State was published in the journal Ecotoxicology, an international journal devoted to presenting critical research on the effects of toxic chemicals on people and the environment.
If you’ve ever seen a seagull snatch some fries or felt their beady eyes on your sandwich in the park, you'd be right to suspect they know exactly when to strike to increase their chances of getting a human snack.
A new study by the University of Bristol is the most in-depth look to date at the foraging behaviours of urban gulls and how they’ve adapted to patterns of human activity in a city.
Before the journey, many birds molt their bright feathers, replacing them with a more subdued palette. Watching this molt led scientists to wonder how feather color changes relate to the migrations many birds undertake twice each year.
A study of the relationships between cognition and the gut microbiome of captive zebra finches showed that their gut microbiome characteristics were related to performance on a cognitive assay where they learned a novel foraging technique. Researchers also identified potentially critical bacteria that were relatively more abundant in birds that performed better on this assay. This correlation provides some of the first evidence of a relationship between a bird's gut microbiome and its brain.
A research team from Osaka University has developed an innovative new animal-borne data-collection system that, guided by artificial intelligence (AI), has led to the witnessing of previously unreported foraging behaviors in seabirds.
