Spatial and Temporal Variability in Migration of a Soaring Raptor Across Three Continents

2019

Disentangling individual- and population-level variation in migratory movements is necessary for understanding migration at the species level. However, very few studies have analyzed these patterns across large portions of species' distributions. We compiled a large telemetry dataset on the globally endangered egyptian vulture neophron percnopterus (94 individuals, 188 completed migratory journeys), tracked across similar to 70% of the species' global range, to analyze spatial and temporal variability of migratory movements within and among individuals and populations. We found high migratory connectivity at large spatial scales (i.e., different subpopulations showed little overlap in winte…

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…
