Hummingbirds use two unique strategies to maneuver through gaps in vegetation, report researchers.

Birds nesting near farmland are half as likely to have at least one fledgling successfully leave the nest when temperatures spike.

A new way to make cellulose gels gets inspiration from how some small birds use spit to hold twigs in place when building nests.

"...as you go from natural areas to human-modified areas, the number of individuals that can persist decreases, which then influences species richness."

Severe space weather events, especially in overcast conditions in autumn, hinder birds' ability to migrate at night, a new study shows.

A population of endangered red-crowned parrots is thriving in urban areas of South Texas, research finds.

Removing road-killed animals that can lead to golden eagles getting hit by cars could help offset the number of birds wind turbines kill.

Some birds that live year round in big cities have eyes that are about 5% smaller. Researchers say bright lights may be the cause.

Vocal learning, problem solving, and brain size among some birds may have evolved in tandem, perhaps as a way to increase biological fitness.

Light pollution at night may lower survival for two backyard bird species. But for one, the American robin, it's the opposite.
