Where have our gulls gone? ( www.bto.org )

Birdwatchers across the UK are being asked to get out and count gulls this autumn, as the British Trust for Ornithology (BTO) continues to monitor populations of these characterful, if sometimes controversial, birds.

While they may be associated with stealing chips, and are frequently characterised as a menace to families enjoying a seaside break, the UK’s gulls are in serious trouble. Researchers from BTO are trying to get to grips with the causes of population declines in our breeding gulls and to monitor those that visit us from further afield.

In autumn and winter, gulls flock together to roost communally on lakes, reservoirs, and estuaries across the UK, in groups that can number many hundreds or even thousands of individuals. Understanding where these roosts occur, and the numbers of birds using them, is key to helping conservation organisations protect these familiar birds.
