(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 ...

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 ...

Bird wings adapted for long-distance flight are linked to their environment and behavior, according to new research on an extensive database of wing measurements. Bird wings adapted for long-distance ...

Migratory birds change how high they fly over deserts and seas. Wing shape, feather color, and heat all play a role in helping them survive.

The dark, smudgy streaks on Xavi Bou's photographs suggest the jerky ink tracks created by a malfunctioning printer, but they actually record the various patterns birds trace while flying in flocks.

In a finding that could change the way scientists think about bird evolution, researchers have found that the shape of bird wings is influenced more by how closely related species are to one another ...

Migratory birds in V-formations master aerodynamic principles, using air currents from leading birds to conserve energy.

Wing color patterns of butterflies perform different signalling functions, from avoiding bird predators to attracting potential mates. Such conflicting natural and sexual selection pressures may ...

Add Yahoo as a preferred source to see more of our stories on Google. Climate change is shrinking our birds. Birds in both North and South America are getting smaller as the planet warms, and the ...

Bird wings adapted for long-distance flight are linked to their environment and behaviour, according to new research on an extensive database of wing measurements, led by the University of Bristol.
