Status of Egyptian vulture (Neophron percnopterus) in Sicily.
2009
La población del buitre Neophron percnopterus en Sicilia se encuentra restringida a los sectores central y oeste de la isla. La población alcanzó cerca de 30 parejas durante el periodo entre 1970 y 1980, auque durante nuestro periodo de estudio (1990–2007), la población tuvo un tamaño promedio de sólo 7 ± 2 parejas más 2 ± 1 individuos no emparejados, con fluctuaciones considerables en los números. Las tasas reproductivas durante nuestro periodo de estudio (juvenil por pareja reproductiva y juvenil por nido exitoso) fueron típicas para una población europea, aunque la tasa de éxito de los nidos disminuyó y el abandono de nidos durante el período 2000–2007 fue el doble del registrado durante…
First description of migration and wintering of adult Egyptian Vultures Neophron percnopterus tracked by GPS satellite telemetry

Capsule Over two years birds showed high territorial and high winter site fidelity in the Sahel.
Food predictability determines space use of endangered vultures: implications for management of supplementary feeding.
2013
Understanding space use of free-living endangered animals is key to inform management decisions for conservation planning. Like most scavengers, vultures have evolved under a context of unpredictability of food resources (i.e. exploiting scattered carcasses that are intermittently available). However, the role of predictable sources of food in shaping spatial ecology of vultures has seldom been studied in detail. Here, we quantify the home range of the Egyptian vulture (Neophron percnopterus), a long-lived raptor which has experienced severe population decline throughout its range and is qualified as endangered worldwide. To this end six adults were tracked by satellite telemetry in Spain d…
Parental investment asymmetries of a globally endangered scavenger: unravelling the role of gender, weather conditions and stage of the nesting cycle
2019
Capsule: In Egyptian Vultures Neophron percnopterus, both sexes invested similar parental effort throughout the breeding period. However, there was variation in the degree of intensity of parental ...
Towards the identification of a new taphonomic agent: An analysis of bone accumulations obtained from modern Egyptian vulture (Neophron percnopterus)…
2014
This paper presents the results of a study of bones recovered in various current Egyptian vulture (Neophron percnopterus) nests in a Mediterranean region of the Iberian Peninsula. The Egyptian vulture, a diurnal, scavenging, rupicolous bird of prey, is one of four vulture species that currently inhabit the Iberian Peninsula. An analysis of the remains found in the nests confirms that it has a heterogeneous diet that includes remains from human activities (butchery and food production) and the carcasses of dead animals, although it is possible that they also prey on small-sized taxa. The taphonomic study determines these birds' capability of transporting, accumulating and altering bone remai…
