Feb. 24, 2023 — Modern birds capable of flight all have a specialized wing structure called the propatagium without which they could not fly. The evolutionary origin of this structure has remained a mystery, but new ...
Sep. 2, 2021 — Bird dispersal movements are thought to depend on complex demographic and genetic factors. Researchers show that there may be a simpler explanation: bird dispersal distances depend on the morphology ...
Sep. 21, 2023 — Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather ...
July 5, 2023 — Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived ...
Dec. 9, 2020 — Molting is thought to be unorganized in the first feathered dinosaurs because they had yet to evolve flight, so determining how molting evolved can lead to better understanding of flight origins. ...
Apr. 9, 2021 — Researchers have discovered that bird blood produces more heat in winter, when it is colder, than in ...
Feb. 4, 2021 — This new paper shows that melanin is more than just something that gives colour to the body. It played an important role in the evolution of warm-blooded animals and helped defined what birds and ...
Feb. 15, 2021 — A new study examines feathers across 249 species of Himalayan songbirds, finding that birds at higher elevations have more of fluffy down than lower elevation birds. Finding such a clear pattern ...
Dec. 6, 2021 — Migratory birds are specially adapted to find their way over extreme distances that represent remarkable tests of endurance. Now, researchers have discovered an unexpected way that migratory birds ...
Feb. 8, 2023 — Scientists have compared the relationship among the strength of flight bones, body mass, and the way modern birds fly to better understand the evolution of flight in birds and extinct animals, such ...
