Local Rarity Description Required
Once a common winter visitor and passage migrant until the 1920s but changed their wintering grounds in Ireland after the drainage of the Zuider Zee in Holland.
Bewick’s Swan is now a very rare winter visitor between November and June to the Sound of Harris (1981), North Uist (1969, 1978, 1989, 1995, 1998), Benbecula (1974, 1985, 1986, 1991, 1992), South Uist with four records (1979, 1980, 1991), and Taransay (1988).
The nine birds on North Uist in November 1989 were also seen on Benbecula and the single bird on North Uist in October 1978 was thought to be the same bird seen on South Uist in February and April 1979.
There have been no records since 1998.
