Factors influencing the breeding density and nest-site selection of the Egyptian Vulture (Neophron percnopterus)

Article

Summary

In northern Spain, density and nest-site selection in the Egyptian Vulture was investigated. The breeding density is positively correlated with the availability of cliffs and independent of trophic resources and human activities. The positive or negative selection of a particular cliff for nesting seems to be determined by intraspecific competition.

Zusammenfassung

Auf einer Kontrollfläche in Nordspanien wurden die Abundanz und die Nistplatzwahl des Schmutzgeiers untersucht. Die Dichte der Brutpaare ist mit der Verfügbarkeit von Felsen positiv korreliert und unabhängig von Nahrungsangebot und Art und Intensität menschlicher Bodennutzung. Die Auswahl bestimmter Felsen als Brutplätze scheint durch intraspezifische Konkurrenz entscheidend bestimmt zu werden.
