Song Is Louder For A Cuckolded Male
2012-08-24 09:11:04

Rock sparrows indicate their age and their reproductive success with their songs and react to infidelity with a higher song volume The song of male songbirds is multifaceted and has two main functions: to repel rivals and to attract mates. Females often pay attention to certain features within a song, such as the presence of special syllables, to assess the quality of the singing male. A team of researchers from the Max Planck Institute for Ornithology in Seewiesen and the University of...

Migrating Songbirds Depart On Time
2012-07-26 07:10:41

A new study by York University researchers finds that songbirds follow a strict annual schedule when migrating to their breeding grounds — with some birds departing on precisely the same date each year. The study, published in the journal PLoS ONE, is the first to track the migration routes and timing of individual songbirds over multiple years. Researchers outfitted wood thrushes with tiny geolocator "backpacks," recording data on their movements. Spring departure dates of birds...

Hunting Birds Favor Uniquely Colored Birds, Study Indicates
2012-04-16 04:12:15

Goshawks tend to focus in on pigeons with unique colors when the birds are travelling in large flocks -- a phenomenon known as the "oddity effect," according to a new study published last Thursday in the journal Current Biology. The study, which was authored by Christian Rutz of Oxford University's Department of Zoology, looked at goshawks as they preyed on feral pigeons in Hamburg, Germany, the institute reported on their website Friday. His goal was to determine whether or not the...

Native American Tribe Granted Permission To Hunt Bald Eagles

The US government for the first time has granted a Native American tribe in Wyoming permission to kill two bald eagles for a religious ceremony, opening the door for future negotiations for native tribes to claim more of the nationally honored birds for their long-suppressed religious freedoms, the tribe said. The US Fish and Wildlife Service (FWS) granted the Northern Arapaho Tribe a permit on March 9 allowing it to either kill or capture and release two bald eagles this year. The permit...

Younger Birds Get No Respect
2012-02-09 04:01:34

When mature male white-crowned sparrows duel to win a mate or a nesting territory, a young bird just doesn't get much respect. Researchers found that older male white-crowned sparrows don't put much of a fight when they hear a young male singing in their territory — probably because the older bird doesn't consider the young rival much of a threat. But a male sparrow will act much more aggressively if it hears a bird of the same age singing in a territory it claims as its own....
