Aggressive-Behavior in 2 Female Peradorcas-Concinna (Macropodidae) and Its Relation to Estrus

Abstract

During oestrus, two captive and isolated female Peradorcas concinna increased their grooming behaviour, especially of the pouch-urogenital area, but the frequency of other behaviours did not change. In encounters, females were very aggressive to other females, males and young during their oestrus, and even killed other adults. Fighting in Peradorcas is unique among macropodids in that it may involve kicking to the lower back while jumping over another animal, as well as attacks from the rear which involve severe biting to the back and neck. The vocalizations associated with these interactions are described.
