A University of Oklahoma study demonstrates for the first time that remote sensing data from weather surveillance radar and on-the-ground data from the eBird citizen science database both yield robust indices of migration timing, also known as migration phenology.
A University of Oklahoma study demonstrates for the first time that remote sensing data from weather surveillance radar and on-the-ground data from the eBird citizen science database both yield robust indices of migration timing, also known as migration phenology. These indices can now be used to address the critical gap in our knowledge regarding the cues that migrants use for fine tuning their migration timing in response to climate.
New research from the Cornell Lab of Ornithology’s Fuller Evolutionary Biology Program shows that, genetically speaking, blue-winged and golden-winged warblers are almost identical. Scientists behind the research say the main differences between the two species are in feather color and pattern, in some cases just a simple matter of dominant or recessive pairings of gene variants, or alleles.
Conservation of intertidal habitat— 65 percent of which has been lost over the last 50 years— is critical to the survival of countless birds during migration on the East Asian Australasian Flyway. In an effort to understand the threats and inform conservation of these areas, scientists from The Institute of Biological Problems of the North (Russian Academy of Sciences) and WCS (Wildlife Conservation Society) have collaborated to identify vital stopover areas for the dunlin, a shorebird known to migrate up to 7500 km (4700 miles) to reach its destination.
Biodiversity Research Institute will participate at the 2016 North American Ornithological Conference, in Washington, D.C., August 16-20. BRI biologists will present current avian research in presentations and poster sessions. BRI’s executive director, David Evers, Ph.D., will participate in a symposium on birds as indicators of ecosystem health and environmental change.
A study published in eLife provides new insights on how bats recognise their surroundings to help them build mental maps.
A DNA analysis of living and extinct species of mysterious New Zealand wrens may change theories around the country’s geological and evolutionary past.
Northern Michigan University students who participated in a recent field ornithology class recorded interactions with more than 175 bird species in various habitats. They saw raptors pepper the sky over Brockway Mountain during the spring migration, owls being banded by researchers at the Whitefish Point Bird Observatory and barn swallows nesting beneath the bridge where the AuTrain River spills into Lake Superior. Some were surprised to spot American white pelicans this far north.
Climate change could make much of the Arctic unsuitable for millions of migratory birds that travel north to breed each year, according to a new international study published today in Global Change Biology.
Research is shedding new light on the causes of divorce in monogamous year-round territorial birds. A Monash University study of the endangered Purple-crowned Fairy-wren has discovered the females are calling the shots when it comes to breaking up.

Research by post-doctoral fellow Alexander Dececchi challenges long-held hypotheses about how flight first developed in birds. Furthermore, his findings raise the question of why certain species developed wings long before they could fly.
Peregrine Falcons, in their normal habitat on isolated cliffs, mate for life. But some 25 pairs now nest on Chicago skyscrapers and bridges, and city living has them in much closer quarters than they used before humans dominated the landscape. A group of Field Museum and University of Illinois, Chicago scientists investigated whether typical breeding patterns hold true for these new city-dwellers and, in a paper published in PLOS ONE, confirmed that even in the big city, the birds that prey together, stay together.
The researchers' observations shed light on the effects of human population expansion on wildlife.
Crows are performing a useful function and keeping our environment free from rotting carcasses, research carried out at the University of Exeter in Cornwall has discovered.
WCS reports that the groundbreaking Bolivian scientific expedition, Identidad Madidi, has confirmed the 1,000th bird species in Madidi National Park, one of the world’s most biodiverse protected areas and a mecca of bird life.
– The Cornell Lab of Ornithology and the Land Trust Alliance are partnering to help protect birds on private lands. The goal of the new Land Trust Bird Conservation Initiative and associated website is to improve conservation for declining species by pairing the bird conservation community with land trusts, which collectively protect more than 24 million acres of private land nationwide.
“Our study shows that we need to learn more about their habits and impacts in the park so the Florida Park Service can make science-based decisions on how to manage these non-native monkeys,” said Steve Johnson, a UF/IFAS associate professor of wildlife ecology and conservation.
Thousands of remarkable fossil birds from the time of the dinosaurs have been uncovered in China. However, most of these fossils are flattened in the rock, even though they commonly preserve fossils.
Sparrows form pair bonds that are normally monogamous, but many females are unfaithful to their partner and have offspring with other males.
