Individual specialization on fishery discards by lesser black-backedgulls ( Larus fuscus )
While seabird–fishery associations are well documented, this research primarily comes from ship-based surveys and consequently individual level responses to discard availability are largely unknown. As part of a long-term study on lesser black-backed gulls (Larus fuscus) in the Netherlands, the fine...
