Déplacements inattendus chez des mâles de Gorgebleue à miroir blanc Luscinia svecica namnetum en période de nidification [Unexpected movements of male Bluethroats Luscinia svecica namnetum during the breeding period]

Abstract : Unexpected movements of male Bluethroats Luscinia svecica namnetum during the breeding period. During a radiotracking survey on 61 different males of Bluethroat Luscinia svecica namnetum from 2012 to 2015 in three different sites, we found that 8 males joined remote areas, at 300 to 900 meters from their regular territory and home range. These movements occurred at dawn and dusk, but also at day. Such movements are not recorded in the literature and we propose four different hypotheses to explain them: the existence of extra-pair copulation places, a male poly-territoriality, the look for food or for a shelter from predators.
