Lesser White-fronted Geese are very rare winter vagrants to Britain, a situation confused by the presence of escapes, some showing evidence of hybridisation. Since the 1981–84 Winter Atlas the species has more than doubled its winter range size but it is impossible to be certain about the provenance of all individuals. However, the fact that ten 10-km squares were occupied during the breeding season casts doubt on these records being of vagrants. Most records were from the southern half of England, a pattern shared with many non-native species. A cluster of records in Norfolk may constitute wild birds migrating with Taiga Bean Geese, but known escapes are also present there.
