The changing status of the lesser black-backed gull Larus fuscus
Major changes in the status of the populations of the large gull species in Ireland have taken place over the past fifteen years. While marked declines have occurred in the numbers of breeding herring gulls Larus argentatus, over more or less the same period there has been a sharp increase in the po...
