Furthermore, the data suggest that females use song rates rather than territory quality in mating decisions. The study indicates a potential role of song rate in the advertisement of territory quality. These features also correlate with song rate of unmated males. Several habitat features are responsible for variation in nesting success. We then related song rate of unmated males to habitat factors in territories and nesting sites in order to examine a possible predictor function of blackcap song for habitat quality. Habitat features determining nest site and song post quality in terms of vegetation cover were compared between successful nests and nests that had suffered predation. Song rate, breeding success, predation on nests and reaction to playbacks were investigated in individual males. ![]() ![]() In this study we examine male song output as a measure of nest site quality in blackcaps ( Sylvia atricapilla).
