Black-headed Gull
02 Mar 2012
Early-returning African migrants like Sand Martin are in the spotlight now, but changes are also afoot with some of our less glamorous migrants. Large numbers of Black-headed Gulls from the Continent winter in Britain and Ireland. Many of these birds will depart soon, whilst our breeders will begin to concentrate at their colonies. These two factors are likely to be responsible for the sharp drop in the reporting rate during March. Look out for Black-headed Gulls that have already attained breeding plumage, like this one photographed in Lincolnshire.
