Tringa nebularia – PIBYDD COESWERDD – Winter visitor and passage migrant
The BTO winter atlas showed that Greenshanks were present in six estuarine 10km squares during the winters of 1981-82, 1982-82 and 1983-84.
The darkest colour represents over 6 birds seen a day. It is likely that the birds concerned were Scottish breeders.
