Diving-Flight Aerodynamics of a Peregrine Falcon (Falco peregrinus)
This study investigates the aerodynamics of the falcon Falco peregrinus while diving. During a dive peregrines can reach velocities of more than 320 km h⁻¹. Unfortunately, in freely roaming falcons, these high velocities prohibit a precise determination of flight parameters such as velocity and acceleration as well as body shape and wing contour. Therefore, individual F. peregrinus were trained...
متن کاملLegacy or colonization? Posteruption establishment of peregrine falcons (Falco peregrinus) on a volcanically active subarctic island
How populations and communities reassemble following disturbances are affected by a number of factors, with the arrival order of founding populations often having a profound influence on later populations and community structure. Kasatochi Island is a small volcano located in the central Aleutian archipelago that erupted violently August 8, 2008, sterilizing the island of avian biodiversity. Pr...
متن کاملCurved flight paths and sideways vision in peregrine falcons (Falco peregrinus).
When diving at prey straight ahead from great distances at high speeds, a peregrine has a conflict between vision and aerodynamics: it must turn its head approximately 40 degrees to one side to see the prey with maximum visual acuity at the deep fovea of one eye, but the head in this position increases aerodynamic drag and slows the falcon down. The falcon could resolve this conflict by holding...
متن کاملShort-term effects of the prestige oil spill on the peregrine falcon (Falco peregrinus).
We have monitored the distribution, population status, breeding success, turnover rate and diet of a Peregrine Falcon population in Bizkaia (North of Spain) since 1997. On the 13th November 2002, the tanker Prestige sunk off La Coruña (NW Spain) causing an oil spill that affected the whole of the Cantabrian Coast and the Southwest of France. The total number of birds affected by the Prestige oi...
متن کاملEvidence of an Urban Peregrine Falcon (falco Peregrinus) Feeding Young at Night
Peregrine Falcons (Falco peregrinus) are typically considered diurnal raptors; thus, the majority of studies on the nesting and hunting behavior of the species have been carried out during the day in rural/natural areas (e.g., Carlier 1993, Carlier and Gallo 1994, Palmer et al. 2003). Nevertheless, early morning (Byre 1990) and late night (Sick 1961) hunting has been observed occasionally in ur...
