... to record the attack trajectories of captive-bred gyrfalcons ( Falco rusticolus ) during their maiden flights against robotic aerial targets, which we compared with existing flight data from peregrine falcons ( Falco peregrinus ). The attack trajectories of both species were well modelled by a proportional...

... utility, surface reconstructions are presented for a barn owl ( Tyto alba ) and peregrine falcon ( Falco peregrinus ) during three instants of gliding flight per bird. The barn owl flew with a consistent geometry, with positive wing camber and longitudinal anhedral. Based on flight dynamics theory...

...Vance A. Tucker ABSTRACT Raptors – falcons, hawks and eagles in this study – such as peregrine falcons ( Falco peregrinus ) that attack distant prey from high-speed dives face a paradox. Anatomical and behavioral measurements show that raptors of many species must turn their heads approximately 40...

...Vance A. Tucker ABSTRACT Some falcons, such as peregrines ( Falco peregrinus ), attack their prey in the air at the end of high-speed dives and are thought to be the fastest of animals. Estimates of their top speed in a dive range up to 157 m s −1 , although speeds this high have never been...

... mentioned above is a straight line for a model peregrine falcon (Falco peregrinus L.) body mounted on smooth struts -struts with convex cross-sectional shapes ranging from streamlined to circular. This finding simplifies the determination of interference drag in three ways: (i) the line can be found from...
