Research into the lives – and deaths – of young rusty blackbirds could help scientists learn more about the complex connections between human activities and the well-being of rapidly declining species, according to a study published today (Oct. 7, 2015) in the journal, “The Condor: Ornithological Applications.”
Can owls and loggers get along? A recent study conducted in Primorye in the southern Russian Far East suggests it’s not only possible, but essential for endangered Blakiston’s fish owls to survive there. The study was conducted by the WCS (Wildlife Conservation Society), the Russian Academy of Sciences, and the University of Minnesota.
The authors monitored the social and foraging behaviors of wild flocks of house finches, a common backyard songbird, and the spread of a naturally-occurring bird disease called Mycoplasmal conjunctivitis, which is similar to "pink eye" in humans but cannot be contracted by humans.
A new study co-authored by scientists at Drexel University, published in the most recent issue of Biological Conservation, reveals the devastating impact of illegal logging on bird communities in the understory layer of Ghana’s Upper Guinea rain forests, one of the world's 25 “biodiversity hotspots” where the most biologically rich ecosystems are most threatened.
Transmission lines that funnel power from hydroelectric dams and wind turbines across Eastern Washington affect greater sage grouse habitat by isolating fragile populations and limiting movement, a new study finds.

Wichita State University microbiology professor Mark Schneegurt and ornithology professor Chris Rogers have discovered that one of North America's most common migratory birds – the Dark-eyed Junco – carries on its feathers a remarkable diversity of plant bacteria, the greatest ever found on wild birds. And while many of these bacteria may be harmful to plants, the bacteria could also be of great benefit.
A group of international researchers published in Functional Ecology found that compared with early birds, late risers are more likely to be cuckolded. The study’s lead author, Dr. Timothy Greives of North Dakota State University, Fargo, said they found that early risers used that time to mate with birds not in their social pair. Melatonin-implanted birds did not sire as many birds and later cared for nestlings fathered by an early riser in their nest. Study results provide insight into the evolution of the body clock.
Researchers have developed vaccines for H5N1 and H7N9, two new strains of avian influenza that can be transmitted from poultry to humans. The strains have led to the culling of millions of commercial chickens and turkeys as well as the death of hundreds of people.
Research by Bournemouth University's John Stewart has found that birds living during the Ice Age were larger, with a mixture of birds unlike any seen today, and many species now exotic to Britain living in Northern England.
Citizen scientists tracking backyard bird feeders helped scientists pinpoint the climate forces that likely set the stage for boreal bird irruptions in which vast numbers of northern birds migrate far south of their usual winter range. The discovery could make it possible to predict the events more than a year in advance.
A Cooper’s hawk, found in Greater Vancouver, is the most polluted wild bird that has been found anywhere in the world. The levels of polybrominated diphenyl ethers (PBDEs) in the contaminated Cooper's hawk were 196 parts per million, significantly higher than those recorded in birds found either in cities in California or in an electronic waste site in China.

New research from a Wake Forest University biologist who studies animal behavior suggests that evolution is hard at work when it comes to the acrobatic courtship dances of a tropical bird species.
The landscaping plants chosen by residents for their yards plays a much greater role in the diversity of native birds in suburban neighborhoods than do the surrounding parks, forest preserves, or streetside trees, say biologists at the University of Illinois at Chicago.
For the first time, the same Golden-winged Warbler has been caught at both a migration hotspot and in his wintering grounds.
A new study published in Urban Ecosystems tries to determine what economic value residents in two comparable cities place on having birds in their backyards and parks. Researchers compared two types of common birds – finches and corvids – in both cities, asking residents how much they would pay to conserve the species and what they spend, if anything, on bird food. In Seattle, that value of enjoying common birds is about $120 million annually and in Berlin, $70 million.

Every year, many bird researchers catch warblers, finches, thrushes and other feathered travelers to better understand their routes and migration patterns. A number of conservation initiatives seek to secure land to help species make their trek thousands of miles southward. But without a collective vision, these efforts may not be enough to protect birds in the Great Lakes region.
What inspires people to support conservation? A new study by researchers at Cornell University provides one simple answer: bird watching and hunting.
A scientific team from WCS, Myanmar’s Nature and Wildlife Conservation Division – MOECAF, and National University of Singapore (NUS) has rediscovered a bird previously thought to be extinct.
The conservation value of growing coffee under trees instead of on open farms is well known, but hasn’t been studied much in Africa. So a University of Utah-led research team studied birds in the Ethiopian home of Arabica coffee and found that “shade coffee” farms are good for birds, but some species do best in forest.
Western Illinois University biological sciences Professor Brian Peer is receiving attention for his research and publication on a bilateral gynandromorph bird found in the wild.
Wildlife biologists at the University of Arkansas have captured and documented the first northern saw-whet owl in Arkansas.
A new study from the Wildlife Conservation Society shows that habitat alteration may be less important than other factors– such as human behavior– in driving the effects of “exurban” development on bird communities. These unexpected results are fueling more questions that may ultimately lead to informed landowners lessening their impacts on local wildlife.
New research shows that mating pairs of the bird species known as great tits become more similar in their hormones over time. The results of this study will be presented at the annual conference of the Society for Integrative and Comparative Biology in West Palm Beach, Florida on January 7, 2015.
A newly published study involving the University of Iowa finds crows have the brain power to solve higher‐order, relational‐matching tasks, and they can do so spontaneously. That means crows join humans, apes and monkeys in exhibiting advanced relational thinking, according to the research.
Since 1998, hundreds and sometimes thousands of dead eider ducks have been washing up every year on Cape Cod’s beaches in late summer or early fall, but the reasons behind these cyclic die-offs have remained a mystery. A team of scientists from Cornell, Tufts University, University of Georgia, the U.S. Geological Survey and the U.S. Fish and Wildlife Service have pinned down one of the agents responsible: a pathogen they’re calling Wellfleet Bay virus (WFBV). Their findings shed light on why eider ducks (also called common eiders) die on Cape Cod every year and offer hints about how the virus spreads.
More than 200 researchers, including a Las Cruces professor, are part of an international collaboration in sequencing DNA for all major groups of birds.
A group of international scientists and researchers investigated how various birds are related genetically.
GAINESVILLE, Fla. --- Nature abhors a vacuum, which may explain the findings of a new study showing that bird evolution exploded 65 million years ago when nearly everything else on earth -- dinosaurs included -- died out.
Birds fly into windows all the time, often killing themselves. The student chapter of The Wildlife Society at Michigan Tech is researching these collisions at buildings on campus, hoping to develop some protective solutions.
Although hummingbirds are much larger and stir up the air more violently as they move, the way that they fly is more closely related to flying insects than it is to other birds.
A new diagnostic technique — resulting from monitoring thousands of courtship calls from songbirds — can be used to safely map the human brain during complex neurosurgery, according to research from Neuroscientists at NYU Langone Medical Center and elsewhere.
Biologists long assumed that one-way air flow was a special adaptation in birds driven by the intense energy demands of flight. But now University of Utah scientists have shown that bird-like breathing also developed in green iguanas – reptiles not known for high-capacity aerobic fitness. The finding bolsters the case that unidirectional bird-like flow evolved long before the first birds.
Unable to fly, nestling birds depend on their parents for both food and protection: vocal communication between parents and offspring helps young birds to determine when they should beg for food and when they should crouch in the nest to avoid a predator seeking an easy meal. A group of researchers has found that ambient, anthropomorphic noise – from traffic, construction and other human activities – can break this vital communications link, leaving nestlings vulnerable or hungry.
Researchers uncovering the secrets of spooky sounds, charismatic voices, nestling birds, traffic noise and more will describe their latest findings during a two-hour live Webcast press event on Wednesday, October 29, 2014. It will be streamed live from the 168th meeting of the Acoustical Society of America (ASA), which takes place this week in Indianapolis, Indiana.
University of Delaware oceanographers have reported a connection between local weather conditions and the weight of Adélie penguin chicks in the Oct. 22 issue of Marine Ecology Progress Series.
Planned wind turbine farms in California --- intended to create new, renewable energy resources --- are endangering the lives of rare birds of prey populations. A geography professor at West Virginia University is monitoring the birds' flight patterns to protect them and preserve the efforts to harvest wind energy.
Over the past two decades, the resident communities of birds that attend eastern North America’s backyard bird feeders in winter have quietly been remade, most likely as a result of a warming climate.
In a new study, scientists examined whether corn and grassland fields could provide both biomass for bioenergy production and bountiful bird habitat. The research team found that grasslands supported more bird species than cornfields did, and new findings indicate grassland fields may represent an acceptable tradeoff between creating biomass for bioenergy and providing habitat for grassland birds.
