Interspecific and intraspecific kleptoparasitic interactions of the bearded vulture (Gypaetus barbatus) at nesting areas

Abstract

Documentamos interacciones interespecificas e intraspecificas de cleptoparasitismo en el quebrantahuesos en los sectores de nidificación. De un total de 54 interacciones, 26 tuvieron lugar en rompederos, 24 en el nido, tres en vuelo y uno en posaderos. Veintidos de las interacciones fueron intraspecificas y las 32 restantes interespecificas con cuervos (Corvus corax), buitres leonados (Gypsfulvus) y águilas reales (Aquila chrysaetos). La mayoria de las interacciones tuvieron lugar en zonas donde el alimento se acumulaba (nidos y rompederos) evitando las acciones directas en vuelo. En el caso de los adultos, este comportamiento podria ser una acción oportunista pero para las aves de <3 años si podria tratarse de una estrategia alimenticia. Puesto que la disponibilidad trófica es suficiente, la población reproductora esta incrementandose y las especies heterospecificas compiten por los mismos sectores de nidificación, el cleptoparasitismo podria estar relacionado con otros factores no relacionados con la obtención de alimento.
