Wie Singvögel auf Feindrufe hassen lernen

Abstract

The question of how territorial calls of the European pygmy owl come to elicit approach and/or mobbing responses from songbirds was investigated in areas both in and out of the owl's distribution. Great tits learned to respond to an artificial 800 Hz pure tone stimulus in both areas when the sound was presented in conjunction with both a multi-species mobbingchorus playback and a live pygmy owl placed near the nest.
