The Size and Composition of Groups in the Red Kangaroo, Macropus rufus

Abstract

Red kangaroos, observed in the field in western New South Wales, were dispersed in small groups which, although aggregated near shelter, food or water, appeared to move independently. The temporal stability of these small groups is not known. Mean group size was 2.6, and more animals were seen in groups of two, three or four than were seen alone. Groups of two were most common, more than half of them containing one female with young-at-foot. Mixed-sex groups with one or several adult males were found.
