Goosander – 1980s winter

Mergus merganser – HWYADEN DDANHEDDOG – Scarce winter visitor. Not recorded in April, May, July and August

The BTO winter atlas showed the 10km squares where Goosanders were recorded 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 4-10 birds seen in a day.
