    Life History

    This is an introduced species from North America that relatively quickly colonised the UK. The UK population is considered resident.

    UK Status

    This was quite a common breeding bird but because of the potential risk of hybridising with White-headed Duck in Spain it was decided to cull the British population, which was very successful. It is now a very scare bird.

    VC55 Status

    Was common but now a very scare visitor (see UK status).
