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...

Ecological dynamics related to energy use and competition drives the seasonal distribution of birds in mountains across the world.

ChatGPT and other AI tools may seem irresistible. But educators should beware, as they could end up trading away the thing that gives them value — the rich experience of slow learning

Large-scale analyses of bird species traits reveal that land-use change reduces resilience of key ecological functions more than previously thought.

Restricted elevational ranges are common across tropical montane species, but the mechanisms generating and maintaining these patterns remain poorly resolved. A long-standing hypothesis is that specia...

An ecosystem energetics approach, quantifying trophic energy flows across species, offers a unified framework for linking animal biodiversity loss to changes in ecosystem function and Earth system pro...

Fire regimes are context-dependent, as are the ways that animals respond. However, most information on animal responses to fire comes from short-term local field studies, which are hard to extrapolat....

Concealed black or white bands on feathers boost the vibrancy of bird plumage
