Melanitta nigra – MOR-HWYADEN DDU – Winter visitor and passage migrant
The BTO winter atlas showed that Common Scoters were present in a few coastal and estuarine 10km squares during the winters of 1981-82, 1982-82 and 1983-84.
The darker the colour, the higher the relative total count for each 10km square. The darkest blue represents more than 96 birds. Up to 420 were recorded in St Bride’s Bay (SM 81 & 82) and 650 off Amroth (SN 10) during this period.
