Abstract

The sexual selection comprises intra and intersexual competition for mates. Studies of bird mate systems have highlighted that extra-pair fertilization (EPF) and brood parasitism are most common strategies. It was long believed that most species of birds would be strictly monogamous, but since the advent of molecular techniques for determining parentage, it has been reported the occurrence of EPF in several groups, and to varying degrees. It was also revealed that intraspecific brood parasitism is much more common than previously thought. These revelations has both stimulated a revolution in the way of thinking about avian mating system and created a need for hypotheses to explain the evolution of these systems. One of the hypotheses, but poorly tested in tropical environments is that asynchrony facilitates the occurrence of these reproductive behaviors. The aim of this study is to determine the frequency of EPF and intraspecific parasitism in White-necked Thrush, Turdus albicollis Vieillot, 1818, in an Atlantic Forest area in São Paulo State, by carrying out molecular tests for determining parentage using microsatellite loci. Using the Breeding Synchrony Index we will test the effect of reproductive synchrony on occurrence of this alternative reproduction strategy. (AU)
