(CN) - A new study on bird wing shape has found a pattern among birds of the same ancestry, called clades, and little correlation among flight styles. Previous wing shape studies have measured bone ...

Geographic and phylogenetic sampling of avian wing-bone morphology. Using measurements from 7366 skeletal specimens, we analyze variation in wing-bone length across 1520 bird species, representing ...

You can know a lot of things about birds just by the shape of their wings. A seafaring albatross, stretching out its sail-like airfoils, lives a very different life from a ground-dwelling antpitta ...

Heliconius charithonia is one of the species of butterflies whose wing patterns scientists scrutinized to better understand the evolutionary process. This butterfly is wild-type; the genetically ...

From geese and pelicans to cranes and cormorants, many birds use a V-shaped flock to master the aerodynamics of long-distance ...

Dark feathers may help birds fly more efficiently. They heat up the animals’ wings and the surrounding air, which might help increase airflow over the wing. Svana Rogalla at Ghent University in ...
