title: Female mate guarding: no evidence in a socially monogamous species.
abstract: To understand the behavioural aspects of sperm competition, the costs and benefits to both sexes should be considered. However, few studies have addressed the costs to females of their social mate engaging in extrapair copulations (EPCs). Measures of female mate guarding have concentrated on female solicitation and copulation; however, females may also control access to their mate by maintaining close proximity, as is common in males. I recorded the maintenance of pair proximity behaviour of an urban population of the socially monogamous European blackbird, Turdus merula, over three breeding seasons. There was no evidence that females guarded their mates to prevent them from engaging in EPCs, nor were there any effects of the potential quality indicators of age, body size or male bill colour on the intensity of mate guarding between individuals. The study adds to a small body of literature suggesting that female mate guarding may be found in (facultatively) polygynous species, but not in socially monogamous ones.
