Social organization of a trio of Bearded vultures (Gypaetus barbatus): Sexual and parental roles

Abstract

El Quebrantahuesos (Gypaetu barbatus) ocasionalmente forma grupos cooperativos (trios). Durante 1991 y 1992 examinamos la conducta reproductora de un trio Pirenaico (NE Espafia). Nuestras observaciones indican que el grupo estuvo formado por una pareja alfa y un macho secundario. El trio exhibió un periodo inusualmente extenso de cópulas donde la hembra copuló preferentemente con el macho alfa, pero también aceptó aparentemente de forma furtiva al macho secundario, en concreto tras la puesta. Fueron observadas algunas cópulas macho-macho comportamentalmente exitosas, si bien el significado de estas es desconocido. Nuestros resultados sugieren que la hembra pudo beneficiarse a través de las cópulas de la inversión parental suministrada por ambos machos. En este contexto, las hembras, debido a sus características físicasy comportamentales podrian ejercer un control social dentro de estos grupos.

This study was supported by the Departament de Medi Ambient of Generalitat de Catalunya.
