A U.S. study suggests migrating birds will stop in any environment where there is adequate food and protection, and not just in large forested areas. Purdue University Associate Professor John Dunning and graduate student Diane Packett conducted the study, which indicates conservation efforts should extend to smaller forested lands to help stabilize declining migratory bird populations. There are strategies for conserving forest for migratory birds, but those strategies emphasize the largest...

U.S. biologists say they've discovered unusual gene activity in the brains of zebra finches occurs after the birds hear a new song from another bird. University of Illinois Professor David Clayton and his colleagues said they determined when a zebra finch hears a new song from a member of its own species, the experience affects thousand of genes, offering a new picture of memory in the songbird brain. Clayton said the finding was a surprise since he hadn't expected to see so many genes...

Scientists have uncovered a bird's nest believed to be 2,500 years old on a cliff in Greenland. The discovery is the oldest raptor nest ever recorded, and the site is still in use today by gyrfalcons, the largest falcon species in the world. Three other nests, each over 1,000 years old, were also discovered, one of which includes feathers from a bird that lived more than six centuries ago.But ornithologists worry that climate change could soon drive the falcons from these ancient...

A new report shows that Scotland's seabird numbers plunged by 19 percent between 2000 and 2008, according to BBC News. The major cause was almost certainly a shortage of food due to a drop in the number of small fish, such as sandeels, according to Scottish Natural Heritage (SNH). SNH said rising sea temperatures were probably affecting the fish populations as well. RSPB Scotland called the figures "deeply worrying," as declines have been greater in areas such as the Northern Isles and down...

Data is crucial to minimizing birdstrikes, researchers sayUsing forensic data from feather remains, scientists have identified the birds that caused the Jan. 15 airline crash into the Hudson River as migratory Canada geese. The study, published online in the journal Frontiers in Ecology and the Environment, will help managers better assess how to prevent such strikes in the future.Led by Peter Marra of the Smithsonian National Zoo's Migratory Bird Center, the researchers applied DNA...

A U.S. biologist says she has discovered bird songs can change as a bird's habitat changes. Elizabeth Derryberry said she made her discovery while conducting her dissertation research at Duke University. She said as vegetation reclaimed formerly cleared land in California, Oregon and Washington during the last 35 years, male white-crowned sparrows have lowered their pitch and slowed their singing so that their love songs would carry better through heavier foliage. This is the first time that...

Some Michigan mammal species are rapidly expanding their ranges northward, apparently in response to climate change, a new study shows. In the process, these historically southern species are replacing their northern counterparts. The finding, by researchers at the University of Michigan, Michigan State University and Ohio's Miami University, appears in the June issue of the journal Global Change Biology. "When you read about changes in flora and fauna related to climatic warming, most of...
