Mallard – 1980s winter

Anas platyrhynchos – HWYADEN WYLLT – Breeding resident, passage migrant and winter visitor

The BTO winter atlas showed that Mallards were present in most 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 over 239 birds both being squares containing estuaries.
