Behaviour

Lesser black-backed gulls breed in Europe and Iceland, but increasing numbers now winter in eastern North America. They feed at sea and on beaches alongside other gulls.

Why they matter

The spread of this gull across the Atlantic over the last half-century is one of the clearest recent changes in North American birdlife, and shows how quickly bird populations can shift their winter ranges.

Reproduction and lifecycle

Nest — A scrape on coastal ground in colonies, in Europe and Iceland
Eggs — Usually three
Incubation — About 24 to 27 days
Chicks — Fed by both parents
Maturity — Adult plumage at about four years
Lifespan — Wild birds over twenty years are recorded

Living around people

  • Like other gulls, they are best left unfed.

Misconceptions

  • All gulls on American beaches are American birds. Some of these came from Europe.
