Counting Common Starlings: Is <i>Sturnus vulgaris</i> invasive in rural South Africa?

Abstract

The numbers of Common Starlings Sturnus vulgaris and indigenous starling species, as well as a subset of other common birds, were recorded from October 2006 to January 2020 at 72 point-count sites along four routes (two urban and two rural) in the Eastern Cape Province of South African. In the rural habitat, Common Starlings were localised at buildings; in the urban habitat, there was no clear indication that their presence influenced the occurrence or abundance of the Red-winged Starling Onychognathus morio, a native species which has colonised towns and nests on buildings. In this region there is little evidence that Common Starlings invade areas that have not been heavily modified by human activities.
