Steve Zack is coordinator of Bird Conservation for the Wildlife Conservation Society (WCS). Thanksgiving is upon us, as families and friends gather for food, drink and conversation.

An air-filled sac within the birds' lungs is believed to increase the force the birds use to power flight muscles while soaring.

Researchers calculated the flight ability of more than 80 ancient cicada species to analyze their evolution over time.

Because muscles and tissues degrade over time, there are very few examples of soft anatomy like this from dinosaurs, says Henry Sharpe, a master's student in the Department of Biological Sciences ...

A new theory of the origin of birds, traditionally believed to be driven by the evolution of flight, is now being credited to the emergence of enlarged skeletal muscles in birds. Their upright two ...

Through dissections of modern birds ranging from Darwin’s finches to Eurasian sparrowhawks, Angst and colleagues studied the anatomy and connection points of the external adductor muscle in ...

To better understand the role of this muscle in reptile anatomy, Persons and Currie dissected the pelvic and post-pelvic muscles of a brown basilisk, spectacled caiman, veiled chameleon, green ...

Like humans, birds have muscles and tendons that stretch over multiple joints, forming a pulleylike structure that can automatically move the connected bones in certain ways.

Humans don't have hollow bones like birds do, so how big would our wings have to be to lift us off the ground?

When turkeys do go aloft, it is not in sustained flights like most other birds, but rather in sudden bursts of short duration. Blood vessels of the leg and thigh muscles contain myoglobin, which ...
