Abstract

Over a period of eleven years (January 1985 – December 1995) approximately 5 000 individuals representing 51 bird species which, potentially, posed a threat to aviation were collected at the Bloemfontein airport. More than half of the species concerned can be considered as medium sized terrestrial birds of which the crowned plover (Vanellus coronatus) is by far the most important. A similar species composition occurred at the Kimberley airport, in contrast to the greater percentage of water associated birds at the Johannesburg airport. Indirectly, food availability appears to be one of the main environmental factors involved in the presence of the five dominant bird species at the Bloemfontein airport.
