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.

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 […]

Post-fledging dependence period and development of flight and foraging behavior in the Egyptian Vulture Neophron percnopterus.

Egyptian Vulture (Neophron percnopterus) Science Article 6 abstract In northern Spain the first flights of fledgling Egyptian Vultures Neophron percnopterus took place between 28 July and 28 August (at the age of 68-80 d). The post-fledging period ended between 29 August and 5 September when the young migrated (at the age of 89-113 d). The […]

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, […]
