The BTO winter atlas showed that Dunlins were present in several 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 over 900 birds.
The distribution is consistent with the Birds of the Estuary Enquiry (BoEE, now WeBS) at that time, with the majority of birds in the inland parts of the Cleddau Estuary complex.The Nevern and Teifi estuaries provided the main wintering grounds in the north of the county.
