The diet of young Golden Eagles Aquila chrysaetos in Corsica: Foraging in a man-made mammal fauna
Golden Eagle (Aquila chrysaetos) Science Article 2 abstract The diet of young Golden Eagles Aquila chrysaetos in Corsica (Western Mediterranean) has been studied by identifying remains and pellets collected at nests after fledging from 1991 to 1996. Ten mammalian species, 17 birds and two reptiles have been identified, of which snakes, Bovidae (mostly Feral Goat […]
The occurrence of reindeer calves in the diet of nesting Golden Eagles in Finnmark, northern Norway
Golden Eagle (Aquila chrysaetos) Science Article 3 abstract To assess the importance of semi-domesticated reindeer Rangifer tarandus calves in the diet of Golden Eagles Aquila chrysaetos, in Finnmark (northern Norway), we collected prey remains at 37 nests over six years (2001-2006). The study area was divided into 1) a fjord area, which is an important […]
Migration and flight behaviour of Honey Buzzards Pernis apivorus in Southern Israel observed by radar.
European Honey Buzzard (Pernis apivorus) Science Article 1 abstract Observations on the schedule, volume and direction of spring and autumn migration of Honey Buzzards Pernis apivorus show that the northern Arava is at the southeastern edge of the species’ main autumn flyway (funneling into the Negev with southwesterly directions), and at the northwestern edge of […]

Use of alternative nests for clutch replacement In the Egyptian Vulture Neophron Percnopterus
Egyptian Vulture (Neophron percnopterus) Science Article 1 abstract Many single-brooded bird species may raise young from replacement clutches after failingin an initial attempt. The rate of clutch replacement among raptors varies depending on their size, latitude and food abundance. In temperate regions it seems to be usual in small accipitrids and falcons and less frequent […]
Sex identification in the Egyptian Vulture by plow cytometry and cytogenetics
Egyptian Vulture (Neophron percnopterus) Science Article 2 abstract The genome size and sex of the Egyptian Vulture (Neophron percnopterus), a sexually monomorphic bird, were identified from blood samples by the use of flow cytometry (FCM). This technique allowed evaluation of the slightly higher amount of DNA content in the homogametic male compared to that of […]

Migrations and sojourn in Africa of Egyptian vultures ( Neophron percnopterus) tracked by satellite
Egyptian Vulture (Neophron percnopterus) Science Article 3 abstract By means of satellite telemetry, the migrations of three young Egyptian vultures (Neophron percnopterus) from France and Bulgaria were studied and data obtained (over 4,300 Argos locations) to describe movement patterns, timing of migration, routes followed, speed of flight and ranging behaviour in Africa.

Growth rates of nestling Egyptian Vultures Neophron percnopterus in relation to brood size hatching order and environmental factors.
Egyptian Vulture (Neophron percnopterus) Science Article 5 abstract Patterns of growth in weight, tarsus and feather (primary) are described for nestling Egyptian Vulture Neophron percnopterus in northern Spain. Maximum increase in weight and tarsus respectively occurred before 40 and 30 d. The primary growth rate was almost constant until fledging (75 d). Second-hatched nestlings either […]
