The Cape Vulture at Colleywobbles: 1977–1997

Abstract

Vernon, C.J. 1998. The Cape Vulture at Colleywobbles: 1977–1997. Ostrich 70 (3&4): 200–202.

In the late 1970s there were about 180 breeding pairs of Cape Vulture Gyps coprotheres at Colleywobbles colony. In the 1980s the colony increased to over 300 pairs, presumably as a result of birds immigrating to the Transkei. In the 1990s the colony declined to about 60 pairs, either through emigration or mortality. The decrease from the 1980s to the 1990s was probably related to a reduction in food supply (carcasses of domestic livestock) as a result of changes in human social activities.
