Iñigo Zuberogoitia, Auteur ; Gorka Burgos, Auteur ; José Antonio González‐Oreja, Auteur ; Jon Morant, Auteur ; José Enrique Martínez, Auteur ; Jabi Zabala Albizua, AuteurTo use vocalizations properly for the estimation of owl population size, it is important to identify how environmental factors affect owl calling behaviour. Here, we analyse how intrinsic and extrinsic factors modify the vocal activity of Tawny [...]
Article
Juan Antonio Gil, Auteur ; Gonzalo Chéliz, Auteur ; Iñigo Zuberogoitia, Auteur ; Pascual López-López, AuteurWe report the first cases of polygyny for the Bearded Vulture Gypaetus barbatus in the central Pyrenees, Spain.

Article
Josep Bosch, Auteur ; José Enrique Martínez, Auteur ; José Francisco Calvo, Auteur ; Iñigo Zuberogoitia, Auteur ; María Victoria Jiménez-Franco, AuteurThe breeding performance of birds of prey is often related to changes in rainfall, which affects the productivity of the environment and the availability of food and may thereby affect chick survival. We investigated the influence of rainfall on[...]
Article
Pascual López-López, Auteur ; Iñigo Zuberogoitia, Auteur ; Manuel Alcantara, Auteur ; Juan Antonio Gil, AuteurCapsule Male bearded vultures tended to disperse closer to natal territories than females with a preferred eastward natal dispersal direction.

Jose A. Martinez, Auteur ; Jose F. Calvo, Auteur ; Jose E. Martinez, Auteur ; Iñigo Zuberogoitia, Auteur ; Jabi Zabala, Auteur ; Stephen M. Redpath, AuteurBonelli's Eagle Hieraaetus fasciatus is one of the most endangered birds of prey in Europe. Despite mounting interest and research, several questions regarding the conservation implications of territory occupancy and site-dependent population re[...]
Article
Jabi Zabala, Auteur ; Iñigo Zuberogoitia, AuteurWe studied the effects of age on breeding performance and survival probability in a peregrine falcon population, using data from a long term monitoring programme (carried out over 16 yr), in which we were able to identify individual birds. We co[...]
Article
Jose Enrique Martinez, Auteur ; Jose Francisco Calvo, Auteur ; Maria Victoria Jimenez-Franco, Auteur ; Iñigo Zuberogoitia, Auteur ; Pascual López-López, AuteurMechanisms regulating colour polymorphism remain largely unknown and detailed investigation is required to explore the biological consequences on population dynamics. This paper presents the first study of the possible connection between colour [...]

Jose E. Martinez, Auteur ; Jose A. Martinez, Auteur ; Iñigo Zuberogoitia, Auteur ; Jabi Zabala, Auteur ; Stephen M. Redpath, Auteur ; Jose F. Calvo, AuteurWe examine the large-scale spatial distribution and the intra- and interspecific interactions in a cliff-nesting raptor community of a semi-arid Mediterranean area in southeastern Spain. The study community was composed of four top avian cliff-n[...]

Iñigo Zuberogoitia, Auteur ; Jose E. Martinez, Auteur ; Antoni Margalida, Auteur ; Imanol Gomez, Auteur ; Ainara Azkona, Auteur ; Jose Antonio Martinez, AuteurIn natural conditions, Griffon Vultures typically show shy behaviour and escape by flying if approached by humans. According to the state-dependent foraging theory, Griffon Vultures should modify their foraging behaviour depending on food availa[...]
Article
Iñigo Zuberogoitia, Auteur ; Jose Enrique Martinez, Auteur ; Jose Antonio Gonzalez-Oreja, Auteur ; Jose Francisco Calvo, Auteur ; Jabi Zabala, AuteurIn raptors, brood size seems to be closely related to the size of prey brought to the nest, the delivery rate and the degree of parental effort. In the case of Peregrine Falcons (Falco peregrinus), any increase in the size of prey is considered [...]
