aerodynamics of wing-assisted incline running in birds

Chukar Partridge (Alectoris chukar) Science Article 6


Wing-assisted incline running (WAIR) is a form oflocomotion in which a bird flaps its wings to aid itshindlimbs in climbing a slope. WAIR is used for escape inground birds, and the ontogeny of this behavior inprecocial birds has been suggested to represent a modelanalogous to transitional adaptive states during theevolution of powered avian flight.
