Résumé :
|
Wetlands and lagoons of the Mediterranean region are important wintering areas for some species of raptors that breed in Europe. We report the abundance, density and habitat choice of raptors wintering in coastal wetlands, lagoons and surrounding habitats of western Greece. Data were collected during roadside surveys. Species abundance was calculated with the kilometric abundance index, while densities were estimated through density surface models. Marsh Harriers Circus aeruginosus and Common Buzzards Buteo buteo were the most abundant raptors recorded, with the former mostly detected in wetlands and the latter on arable land. Nearly all wintering Marsh Harriers were adult females and immatures. Few Kestrels Falco tinnunculus were detected. A flock of 28 Greater Spotted Eagles Clanga clanga was observed roosting at the Amvrakikos gulf. Marsh Harriers and Common Buzzards were the most abundant wintering raptors recorded in Greek coastal wetlands. Few records of Kestrels are consistent with previous suggestions of interspecific competition with Common Buzzards, combined with the greater ability of Common Buzzards to cross water barriers, which may influence their relative wintering distribution in the Mediterranean basin. The importance of Greek coastal wetlands was confirmed as one of the most important wintering areas for the Greater Spotted Eagles in the Mediterranean Basin.
