Self-foraging vs facilitated foraging by Lesser Black-backed Gull (Larus fuscus) at the Frisian Front, the Netherlands
The Lesser Black-backed Gull (Larus fuscus Linnaeus, 1758) is a surface feeder with a broad prey spectrum that forages in the North Sea on subsurface pelagic fishes and crabs swimming within 0.6 m of the sea surface. In July 2006 and in July/August 2009 we surveyed the Frisian Front area in the sout...
