Behaviour of Bachelor Males of the Przewalski Horse (Equus ferus przewalskii) at the Reserve Askania Nova

Abstract

Zusammenfassung Das Ziel dieser Studie war, das Verhalten von Przewalskipferden bei hoher Besatzdichte in einer Junggesellengruppe auf einer Flache von 3,5 ha zu untersuchen. Die Gruppe bestand aus 16 mannlichen Tieren im Alter von 5 bis 16 Jahren. Verhaltensdaten wurden uber 18 Tage gesammelt, insgesamt 216 h. Funfzehnminutige fokussierte Tierbeobachtung wurde angewendet; jedes Pferd wurde drei Mal am Tag beobachtet, insgesamt 45 Minuten. Das Auftreten von 25 Verhaltensweisen wurde aufgezeichnet und das Raumverhalten wurde untersucht indem “nachste Nachbar” aufgezeichnet wurde. Die Gruppe teilte sich in vier Untergruppen; was fruhere Ergebnisse von der Teilung von Junggesellengruppen (n≥10) in zwei oder mehr Untergruppen unterstreicht; vorausgesetzt die Gruppen enthielten mannliche Tiere uber 5 Jahre. Die gesamte Frequenz der sozialen Interaktionen war 14,6±1,1 Pferd/ Std. Obwohl die Besatzdichte der Gruppe in dieser Studie hoher war als in anderen Zoos, verhielten sich die Tiere nur 3,6 Pferd/ Std agonistisch. Am haufigsten wurde freundliches Sozialverhalten beobachtet. Diese Studie zeigt Moglichkeiten einige investigative Verhaltensweisen (markieren, flehmen, olfaktorische Erkundung, etc.) als Indikator fur die soziale Stellung des Tieres in einer Gruppe zu verwenden.
