Vagrant
Mathew (1984) records one shot from a small flock near St David's in July 1892, a year in which there was a widespread invasion of north-west Europe by Ruddy Shelducks which can be regarded as truly wild birds.
Single birds at Newgale in 1955 and at the Nevern Estuary in 1979, the latter courting a female Shelduck, were of suspect origin, and one at the Gann from 1989 to 1992 was known to have come from a nearby collection.
