Gulls are medium to large-sized birds, often in flocks associated with coastal areas,
sometimes feeding inland on tips, particularly in winter when our native birds populations
are swollen by immigrants from the continent and elsewhere.
During the 20th Century, gull numbers have increased rapidly. In inland localities,
especially outside the breeding season, gulls often roost 'm many thousands on large
bodies of water such as reservoirs or flooded gravel pits. All species, when inland,
depend on domestic refuse for food, although Black-headed and common gulls also feed
on agricultural land.
Over the past twenty years or so, Herring Gulls - and in some cases lesser Black-Backed
