Several populations of Black Skimmers (Rynchops niger), colonial waterbirds with a tactile foraging strategy, are declining. Improving our limited knowledge of Black Skimmer foraging ecology has become critical to inform conservation decisions. Black Skimmers were GPS-tracked from the Isles Dernieres Barrier Island Refuge in coastal Louisiana, USA, from 27 June-1 July 2013 and 30 May-2 June 2016, to shed light on their foraging movements during the breeding season. Black Skimmers foraged almost exclusively at night, as far as 16 km from the colony in the coastal marshes of Louisiana, in a home range of 86-256 km². Additional movement data are needed to identify areas of conservation need and provide a basis for future studies of skimmer response to environmental changes.
