Hummingbird courtship displays reveal limits to avian flight performance
Meeting Abstract 105.4 Wednesday, Jan. 7 Hummingbird courtship displays reveal limits to avian flight performance CLARK, CJ; UC Berkeley cclark@berkeley.edu Courtship displays are a common feature of breeding behavior. While the information these displays convey between suitors and potential mate remains debated, the remarkable behaviors that result can be used to study the limits of locomotor performance. […]
Flight muscle function during takeoff, landing, and mid-flight, in the pigeon Columba livia
Meeting Abstract 105.5 Wednesday, Jan. 7 Flight muscle function during takeoff, landing, and mid-flight, in the pigeon Columba livia BERG, Angela M*; BIEWENER, Andrew A; Harvard University aberg@oeb.harvard.edu In order to achieve different modes of flight, such as takeoff and landing, a bird must move its wings differently. Variation in wing motion requires corresponding variation in activation […]
