Flight performance during hunting excursions in Eleonora's falcon Falco eleonorae.
Among birds, falcons are high-performance flyers, in many cases adapted for aerial hunting and hence suitable targets for investigating limits to flight performance. Using an optical range finder, we measured flight tracks of Eleonora's falcon (Falco eleonorae), a species breeding in the Mediterranean region and specialised for hunting autumn passage bird migrants, when commuting between their ...
متن کاملBRIEF COMMUNICATION Thyroid hyperplasia in a saker falcon (Falco cherrug)
An adult female saker falcon (Falco cherrug) presented to our falcon medical and research hospital with intermittent regurgitation, dyspnea, and squawking sound. Physical, radiographic, and endoscopic examination revealed a markedly enlarged thyroid gland. Hematological and blood biochemical results were within normal ranges apart from a slight increase in creatinine phosphokinase and aspartate...
متن کاملDiving-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 کاملDetection of Borrelia burgdorferi in a Sick Peregrine Falcon ( Falco peregrinus ) – A Case Report
The importance of Lyme borreliosis, a tick-borne disease caused by the bacterium Borrelia (B.) burgdorferi sensu lato, is constantly increasing. It is the most frequent arthropod-borne disease in the northern hemisphere today. Numerous studies about the prevalence of B. burgdorferi in ticks have been published. A review summarising 1,186 abstracts on epidemiological studies of the tick I. ricin...
متن کاملLandscape-scale spatial distribution of the Lanner Falcon (Falco biarmicus feldeggii) breeding population in Italy.
Falco biarmicus feldeggii is one of the most threatened taxa in Europe. Its global population is estimated at a few hundred pairs unequally scattered in a vast and fragmented area stretching from Sicily to the Caspian Sea. Most recent counts showed that Italy hosts a large part (>25%) of the whole population. Consequently, Italian authorities promoted a national action plan. In this framework, ...
