Distribution pattern among Golden Eagle Aquila chrys tos and Bonelli s Eagle Hiera tus fasciatus in the Castellon province.
Golden Eagle (Aquila chrysaetos) Science Article 1 abstract Aims: Spatial distribution patterns of Golden Eagle Aquila chrys tos and Bonelli s Eagle Hiera tus fasciatus have been analyzed in a sympatric Mediterranean area.Location: Castellon province and the Teruel border area, in the M strazgo region. Methods: The nearest neighbor distance has been taken as an […]
Eagles on the Swedish mountain tundra-diet and breeding success in relation to prey fluctuations
Golden Eagle (Aquila chrysaetos) Science Article 4 abstract We studied the diet and the relationship between prey density fluctuations and breeding success of a Golden Eagle (Aquila chrysaetos) population on themountain tundra region of northern Sweden.We used a new PCR basedmethod to analyse theDNAin bone fragments fromGolden Eagle prey remains. This allowed us to accurately […]
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 […]
Organization and Variation of the Mitochondrial Control Region in Two Vulture Species, Gypaetus barbatus and Neophron percnopterus
Egyptian Vulture (Neophron percnopterus) Science Article 7 abstract We report the first entire mitochondrial DNA (mtDNA) control region sequences in two endangered vulture species, the bearded vulture (Gypaetus barbatus) and the Egyptian vulture (Neophron percnopterus). Results showed that the general organization of vulture control regions was very similar to other birds, with three distinct domains: […]
Factors influencing the distribution, abundance and nest-site selection of an endangered Egyptian vulture (Neophron percnopterus) population in Sicily
Egyptian Vulture (Neophron percnopterus) Science Article 8 abstract The Egyptian vulture (Neophron percnopterus) breeds in Sicily and, in 22 years of monitoring, has shown a decline followed by a slight recovery. We used Generalised Linear Models to predict: (1) the distribution range, (2) the habitat selection within the range, (3) the quality (i.e., occupation rate, […]
Levels of polychlorinated biphenyls andorganochlorine pesticides in serum samples ofEgyptian Vulture (Neophron percnopterus) from Spain
Egyptian Vulture (Neophron percnopterus) Science Article 9 abstract Concentrations of 23 polychlorinated biphenyls (PCBs), p,p0-DDT and two of its metabolites, p,p0-DDE and p,p0-TDE have been measured in serum samples of up to 1 ml of Egyptian Vulture (Neophron percnopterus) gathered from five populations in Spain.

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 […]
Food of the Egyptian Vulture (Neophron percnopterus)in Biscay
Egyptian Vulture (Neophron percnopterus) Science Article 4 abstract We studied the diet of the Egyptian Vulture in Biscay, northernIberian Peninsula, between 2000-2003. We monitored adults in territories,searched for nests, and collected food remains in nest and platform. We collectedand identified a total of 143 prey remains, and classified them into 32 categories.
