Résumé :	Seabirds are long-lived birds that exhibit very high levels of parental investment, and male parental care is indispensable. Seabirds have comparable breeding and life history parameters, being colonial, long-lived, and exhibiting little or no sex dimorphism. It is thought that these characteristics explain why seabirds exhibit a uniformly low level of extra-pair paternity. However, among the relatively few seabirds that have been studied to date, some regularly engage in extra-pair copulations, and the reasons for such inter-specific variability remain unclear. We here analyse paternity in a small sub-Antarctic seabird, the Thin-billed Prions Pachyptila belcheri, using species-specific microsatellites as genetic markers. We found that 7 of
