In the current context of the anthropocene, the original habitats of many species have been modified or destroyed. Animals may be forced to move from their original habitats, either to refuge habitats that are suboptimal natural habitats, or to substitution habitats that are anthropogenic. The quality of refuge habitats may be lower than that of the original ones, whereas substitution habitats may be of a similar or even better quality. Here, we test this hypothesis empirically, using the example of coastal populations of the bluethroat, Luscinina svecica namnetum. In a radio-tracking survey, we compared the home-range sizes (considered here a proxy of habitat quality) of the breeding males in their original (coastal saltmarshes), refuge (inland reedbeds) and substitution (coastal salinas) habitats. We found that home ranges are up to 15 times larger in the substitution habitat than in the original one, and intermediate in the refuge habitat, suggesting that substitution habitats have the lowest quality and original habitats the highest. To date, most studies and
conservation programs related to this species have focused on its substitution habitats. This result challenges the interest of focusing on anthropogenic habitats when studying and conserving such a species, because such habitats may only be low-quality substitutes.

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 {\textquotedblleft}hidden leks{\textquotedblright}, a male poly-territoriality, the look for food or for a shelter from predators.
