BirdLife International’s report on the state of the world's birds — trends, pressures, and conservation responses.

Nature Ecology & Evolution - A reconstruction of the evolutionary history of passerine body plans over the past ~50 Myr shows rare bursts of phenotypic innovation near the origin of major...

Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as colorati...

Millions of years ago, rare hybridization events ignited the genetic sparks that contributed to the bright yellow colors of some birds in the modern wood-warbler family.

Habitat loss and fragmentation are among the greatest threats to biodiversity. Here the authors show that habitat quality of the surrounding landscape can also affect demographic rates and population ...

Abstract. Genomic data can provide valuable insights into the evolutionary history of rapidly diversifying groups and the genetic basis of phenotypic trait

The raptors help keep predators away from the tiny birds, new research shows.

The Phylogeny Explorer offers a captivating experience for exploring avian evolution, discovering closely related species, and grasping the timescales at which they evolved.

By listening in on their nightly hunts, scientists discovered that small, fringe-lipped bats are unexpectedly able to efficiently take down prey nearly their own size.

Here, the authors combine ancient DNA, stable isotopes, and computational modeling to study colorful feathers from a pre-Incan tomb in Peru. They identify four species of parrots, which were likely ca...
