A king vulture chick at the Bronx Zoo is being hand-raised using a technique developed more than 40 years ago which helps prevent the young bird from imprinting on humans.
Since the first recorded case of highly pathogenic avian influenza H5N1 鈥� commonly known as avian flu or bird flu 鈥� in 1996, Ian Wilson, professor of structural biology at Scripps Research, and his colleagues have been closely tracking the evolution of several key proteins using SSRL. Recently, Wilson鈥檚 team investigated the evolution of a protein that plays a crucial role in H5N1鈥檚 ability to transmit between species. Their analysis found that the protein is susceptible to a mutation that could help the virus attach to human cells, potentially increasing the risk of human transmission. The findings 鈥� published in Proceedings of the National Academy of Sciences 鈥� underscore the need for ongoing monitoring of H5N1鈥檚 evolution.
Beneficial bacteria could enhance chickens鈥� health and reduce infection risk
In the newly published study, 鈥淪ix-decade research bias towards fancy and familiar bird species,鈥� a team of researchers studied nearly 300 North American species of passerines and near-passerines.
A federally funded project analyzing temperature, light pollution, and bird and mosquito abundance aims to pin down how these and other factors affect West Nile virus transmission. The ultimate goal is to advise health departments of the best time of year to kill mosquitoes that transmit the virus.
3D modeling shows how larger brains triggered changes in jaw muscles and joint mechanics that powered a flexible feeding system for modern birds.
Hummingbirds are often highly aggressive and territorial, but in the tough terrains of the Andes Mountains, BGSU researchers found a species is living cohesively with its peers
In a recent commentary published in Nature Medicine, Tulane University virologist Bob Garry outlined the steps he sees as essential to preventing H5N1 from developing human-to-human transmission 鈥� and what strategies should be employed if the virus is able to evolve into a greater threat.
Large birds 鈥� our closest relations to dinosaurs - are capable of technical innovation, by solving a physical task to gain access to food.
In collaboration with the Biodiversity Initiative, BRI biologists are conducting mercury sampling in the small Central African country of Equatorial Guinea. The team is conducting some of the first dedicated sampling of birds to assess mercury exposure in Central Africa.
The disease is decimating bird populations and spreading into mammals, but human infections remain rare.
An international team of researchers reports on unique bird skull in "Palaeontologia Electronica". The flightless bird called Diatryma roamed the Geiseltal region in southern Saxony-Anhalt in Germany around 45 million years ago. The only other place that a similar skull fossil has been found is the USA.
Following the recent outbreak of highly pathogenic avian influenza (HPAI) in Accomack County, Virginia, poultry owners are being urged to take action to protect their flocks. Virginia Cooperative Extension is joining the Virginia Department of Agriculture and Consumer Services in offering guidance to help prevent the spread of the virus in Virginia.
Evidence from over 18,300 hours of recorded flight calls suggests songbirds may 鈥渢alk鈥� to other species as they migrate, forming social connections and 鈥� just maybe 鈥� exchanging information about the journey.
The price of eggs is often an inflationary barometer. The H5N1 bird flu has caused those prices to soar.Egg shortages due to H5N1 bird flu have created record-breaking daily price increases. The latest avian influenza has slashed U.S. egg production by 5%, according to Karyn Rispoli, managing editor of Urner Barry鈥檚 Egg Division.
Birds make sounds to communicate, whether to find a potential mate, ward off predators, or just sing for pleasure.聽聽But the conditions that contribute to the immense diversity of the sounds they make are not well understood. Researchers at the University of Wisconsin鈥揗adison have conducted the first-ever global study of the factors that influence bird sounds, using more than 100,000 audio recordings from around the world.
