摘　　要：Migratory connectivity describes the linkage between breeding and nonbreeding sites,having major ecological implications in birds:1 season influence the success of an individual or a population in the following season.Most studies on migratory connectivity have used large-scale approaches,often considering regional populations,but fine-scale studies are also necessary to understand colony connectivity.The lesser kestrel Falco naumanni,an insectivorous migratory raptor which form colonies during the breeding period,was considered to have strong connectivity based on regional populations.However,no small-scale studies on migratory connectivity have been conducted.Therefore,we GPS(Global Positioning System)-tracked 40 adult lesser kestrels from 15 different Spanish breeding colonies,estimating the overlap index between home ranges and the distance between their centroids.It was found that lesser kestrels from the same breeding colony placed their nonbreeding areas at 347±281 km(mean±standard deviation)away from each other(range=23-990),and their home ranges over-lapped by 38.4±23.6%.No differences between intra-colony and inter-colony metrics were found,which suggests that lesser kestrels from the same breeding cluster do not overwinter together,but they spread out and mixed independently of the colony belonging throughout the nonbreeding range of the species.Uitimately,this study highlights the importance of performing connectivity studies using fine-scale approaches.
