Résumé

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 900meters fromtheir regular territory and home range. Thesemovements 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 “hidden leks”, a male poly-territoriality, the look for food or for a shelter from predators.
