Individual specialization on fishery discards by lesser black-backed gulls (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...

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-scale movements of adults were tracked with GPS tags throughout the breeding period. The aim of this study was to determine if lesser black-backed gulls were utilizing fishery discards in the Wadden Sea and to examine possible consequences of this behaviour. Within the Wadden Sea during weekdays, tracked birds predominately associated with zones where fishing vessels are known to operate (deep gullies). Across all individuals combined (n = 40), there was a significantly reduced use of the Wadden Sea during weekends when the fleets were not operating.
