The lesser sandeel Ammodytes marinus is a key prey species for many avian predators in the North Sea, and is the target of the largest single species fishery in the area. This has led to concern about the potential impact of the fishery on seabirds.... Read More about Diet and breeding performance of black-legged kittiwakes Rissa tridactyla at a North Sea colony.

Evidence of intra-specific competition for food in a pelagic seabird (2001)
Journal Article

The factors affecting the population dynamics of seabirds have long intrigued biologists. Current data suggest that density-dependent depletion of prey during the breeding season may regulate population size. However, much of the evidence for this ha...
