Lesser Black-backed Gull

Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs. Steve Backshall presents the lesser black-backed gull.

These smart gulls are charcoal grey on top and white beneath. Like herring gulls, their close relatives LBBs have moved into urban areas and now breed on flat roofs in the centre of cities. It seems almost any flat surface will do. In just three hours, one bird in Gloucester built a nest on a car roof and laid an egg in.
