Across Africa’s open grasslands, the secretary bird (Sagittarius serpentarius) stands apart from other birds of prey. With crane-like legs and the hunting instincts of an eagle, it stalks the ground ...

Birds are the only dinosaur lineage that survived until today. About 66 million years ago at the Cretaceous–Paleogene (K–Pg) boundary, a mass extinction event destroyed all non-avian dinosaurs, ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of studies ...

An international team of scientists has created the largest and most detailed bird family tree ever, spanning 93 million years and representing 92% of bird families species, using cutting-edge ...

Genomic anamolies dating back to the time of the dinosaurs misled scientists about the evolutionary history of birds. An enormous meteor spelled doom for most dinosaurs 65 million years ago. But not ...

The study found that bird species who nest in tree cavities have independently evolved heightened aggression across lineages, particularly in females. Scientists have long wondered whether evolution ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...
