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. Bernd-U. Meyburg, Max […]
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, […]
Egyptian Geese Alopochen aegyptiacus moulting on Dassen Island, South Africa
Egyptian Goose (Alopochen aegyptiacus) Science Article 1 abstract Egyptian Geese have increased in numbers in the Western Cape in recent decades, and they are considered agricultural pests in the Swartland region, the grain-producing area on the mainland adjacent to Dassen Island (Hockey et al. 1989). It is possible that traditional moult sites on the mainland […]
Current status of the threatened Dupont’s lark Chersophilus duponti in Spain: overestimation, decline, and extinction of local populations
Duponts Lark (Chersophilus duponti) Science Article 2 abstract The European population of Dupont’s lark Chersophilus duponti, restricted to Spanish steppe, was estimated to be 13,000 pairs in c. 50 populations in 1988. There is, however, recent evidence that this number was overestimated because of the previous use of line transects for estimating population sizes. In […]
Habitat-suitability modelling to assess the effects of land-use changes on Dupont’s lark Chersophilus duponti: A case study in the Layna Important Bird Area
Duponts Lark (Chersophilus duponti) Science Article 1 abstract Habitat-suitability modelling is being increasingly used as a tool for conservation biology. Although studies at large spatial scales are more appropriate for reserve design and management, there is a scarcity of published work on local, high-resolution applications of such models. In this work we develop high-resolution habitat […]
Two new calls from the Dupont’s Lark Chersophilus duponti and imitations by other alaudids: ecological and monitoring implications
Duponts Lark (Chersophilus duponti) Science Article 4 abstract The Dupont’s Lark Chersophilus duponti isone of the rarest Palearctic passerines, whosedistribution is confined in Europe to the remainingsteppe plateaux and lowlands of the Iberianpeninsula (Cramp, 1998). As a consequenceof recent data that revealed that Spanishpopulations are much smaller than previouslyestimated, the species is currently considered
