AbstractThe application of Game Theory to the study of behaviour has shown that it is possible, in theory, to have stable equilibria with individuals in a population behaving in different ways. In order to test for colony type selection or "nesting strategies" in this species, breeding success, site tenacity and mate selection should be monitored on a long term basis. An investigation of the reproductive biology and behaviour of Great Black-backed Gulls was undertaken to provide preliminary data to design such project. - The effects of habitat or colony type selection on reproductive output was assessed in a one year study by comparing the breeding biology and behaviour of Great Black-backed Gulls in two different environments, namely a mono-specific and a mixed-species colony. Many aspects of the breeding biology of Great Black-backed Gulls were similar between colonies but important behavioural differences were observed. -- There is some evidence that colony type selection fits the model of "ideal free distribution" (Fretwell and Lucas, 1970) and acts as a "breeding strategy" in Great Black-backed Gulls. However, energetic studies should be undertaken to assess costs and benefits of the proposed strategies.
