Branta leucopsis – GWYDD WYRAN – Winter visitor and passage migrant.
The Teifi Estuary holds, on a rolling five-year average, the second-largest winter population in Wales.
The 1980s counts are for a flock that spent the winters between Skomer and Marloes Mere (see Barnacle Goose – 1994 for more details).
The counts since 2005 refer mainly to a feral flock breeding Cardigan Island, and wintering on the Teifi Estuary. One or two birds are sometimes seen elsewhere, usually in the company of other geese. As the geese often feed away from the estuary, they may not be present for WeBS counts.
