Warmer springs mean more offspring for prothonotary warblers

Climate change contributes to gradually warming Aprils in southern Illinois, and at least one migratory bird species, the prothonotary warbler, is taking advantage of the heat. A new study analyzing 20 years of data found ...

Warbler coloration shaped by evolution via distinct paths

Two genes that are important for the diverse colors and patterns of warbler plumage have evolved through two very different processes, according to a new study led by Penn State researchers. These evolutionary processes could ...

What determines a warbler's colors?

A new study has narrowed down the region of the genome that drives the black color in throat and face of warblers by studying the hybrid offspring produced when two species mate. The hybrids of golden-winged and blue-winged ...

When warblers warn of cowbirds, blackbirds get the message

This is the story of three bird species and how they interact. The brown-headed cowbird plays the role of outlaw: It lays its eggs in other birds' nests and lets them raise its young—often at the expense of the host's nestlings. ...

Understanding why songbirds choose their homes

New research by University of Alberta biologists uses a new approach to modelling the populations of six species of songbirds in Canada's boreal forest—and the results show that standard modeling methods may not be accurately ...

New insights into genetic basis of bird migration

A gene newly associated with the migratory patterns of golden-winged and blue-winged warblers could lend insight into the longstanding question of how birds migrate across such long distances.

Study reveals key locations for declining songbird

Many of North America's migratory songbirds, which undertake awe-inspiring journeys twice a year, are declining at alarming rates. For conservation efforts to succeed, wildlife managers need to know where they go and what ...

Songbirds set long-distance migration record

Researchers at Lund University in Sweden have studied flight routes to determine how far willow warblers migrate in the autumn. The results show that the willow warbler holds a long-distance migration record in the ten-gram ...

Discovery: Rare three-species hybrid warbler

Scientists have shown that a bird found in Pennsylvania is the offspring of a hybrid warbler mother and a warbler father from an entirely different genus—a combination never recorded before now and which resulted in a three-species ...
