AbstractWrens. Troglodytes troglodytes, are highly polygynous passeriness. Males build cock nests that are displayed to females and function as a mate-choice cue. Males with large numbers of nests are more likely to attract females than males with fewer nests. To be useful to females a cue used in mate choice must contain information. One way to evaluate the information content of such a cue may be to examine the factors that influence its size. The number of nests was predicted on territories with known building rates (immigration) and nest destruction rates (death) using an immigration death function. This analysis suggested that if only building rate and destruction rates were considered then the number of nests on territories was consistently overestimated. In 1994 an experiment was conducted in which nest-site availability was manipulated. Males provided with additional nest sites built more nests and continued to build later in the year resulting in longer nest-building periods that controls. The converse was found when nest sites were experimentally removed. This suggested that the numbers of nests that could be constructed on a territory was limited by habitat structure. None of the morphological characters considered here significantly influenced the number of nests built by males. Therefore, the information content of this mate-choice cue will be primarily about characteristics of the habitat on the territory rather than characteristics of the male.
