(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 ...

Bird wings adapted for long-distance flight are linked to their environment and behavior, ... "This geographic pattern is really striking.

Bird wings, unlike stiff airplane wings, are flexible and change shape during flight. ... "There's no existing hypothesis to explain that pattern," Clarke said.

In this study, published Tuesday in the journal Integrative and Comparative Biology, researchers observed these birds mid-flight and recognized that those from the same migration patterns communicated ...

Soaring birds. They exposed osprey, gannet and back-blacked gull wings to wind speeds of 6, 12 and 18 metres per second, similar to the birds’ natural flight speeds.

Climate change is shrinking our birds. Birds in both North and South America are getting smaller as the planet warms, and the smallest-bodied species are changing the fastest, a study reported Monday.

Naturally, they looked to birds for inspiration. Albatrosses are a group of very large seabirds that can soar as far as 16,000 kilometers (10,000 miles) in a single journey ().Albatross wings are ...
