Oystercatcher – 1980s winter

Haematopus ostralegus – PIODEN Y MOR – Breeding resident and passage migrant

The BTO winter atlas showed that Oystercatchers were present in all 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 45-225 birds.
