| Abstract | Since 1994, the last remaining black grouse population (Tetrao tetrix) declines in the High Fens Natural Reserve. Despite led restoration works, this species is still dramatically endangered. These two last years, black grouses have been translocated from Sweden to restore and prevent the disappearance of this emblematic species. This work aims at studying this reinforced population movements into space and time by, on the one hand, a visual tracking and, on the other hand, by a radio-tracking. Collected data by the latter were analysed on eight individuals equipped with UHF, UHF/GSM et GSM tags, over a period of two months. This kind of data is hitherto unseen for the species study, both at national and European scale. Results show that, despite a high mortality rate for 2018, the environment seems to be suitable and sufficient for translocated black grouses. They adopt a rhythm of life deemed "normal": they use appropriate areas and habitats, corresponding to those used by Belgian black grouses and food availability. They interact with each other and display on ancestral leks. Finally, in two successive years, at least two hens nested in the same habitat. One of them established itself in known nesting site. These results do not show in any way populational tendencies but allow however to bring specific generalities to translocated individuals. |
