La migración como factor que determina la duración de los cuidados parentales durante el periodo de dependencia en rapaces: el caso del alimoche ("Neophron percnopterus") en las Islas Baleares (España)

Resumen

Sedentary Egyptian vulture population was studied during their post-fledging dependence period in Balearic Islands (Spain) compared with a migratory population in northern Iberian Peninsula. Fledging age, independence age and length of postfledging dependence period are similar in these two populations. Some studies are indicated that length of post-fledging dependence period are determinate by the necessity of migrant species begin his migration, and this migrant species would show length post-fledging dependence period more shorts. Our results show that sedentary populations have similar post-fledging dependence period that migration population.
