Pembrokeshire Avifauna committee in 1980s BTO winter atlas, GHR, Oystercatcher

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.
