Status Summary
Apart from an indigenous population in north-west Scotland and Western Isles, as a breeding bird, the Greylag Goose is an introduced species throughout the UK. Breeding season monitoring information was sparse before the early 1990s, but the population shows evidence of increases since then. Winter monitoring by WeBS shows a continuing long-term increase (Pollitt et al. 2000).
