AbstractIn most bird species females can determine whether copulation takes place or not, and whether they result in cloacal contact and sperm transfer ( BIRKHEAD & MØLLER1992). Females frequently reject copulation attempts, which suggests reproductive conflict of interest between the sexes (WAGNER1996). Ecological pressure, phylogeny and conflicts of interest are the factors that may have led to the existence of a wide variety of mating systems in birds (DAVIES et al. 1995). In polyandry, where sperm competition is obvious, males try to achieve the highest possible number of copulations in order to ensure paternity. On the other hand, some polyandric females manipulate males via copulations during the breeding cycle in order to gain material benefits. Females that are associated with more than one male accept copulations with subordinate males in order to obtain a greater amount of parental care (BIRKHEAD 1998).
