摘要
We provide evidence for predation by the Common Egg-eater (Dasypeltis scabra) on the eggs of three species of ground-nesting birds, namely African Pipit (Anthus cinnamomeus), Cape Longclaw (Macronyx capensis) and Common Quail (Coturnix coturnix). Although egg-eaters have been recorded as egg predators of several bird species in the wild - including a few other ground-nesters such as lapwings, francolins, sandgrouse, gulls and terns - we present the first evidence of such predation in the Mesic Highveld Grassland Bioregion of South Africa.
