Tringa ochropus – PIBYDD GWYRDD – Passage migrant and winter visitor
The BTO winter atlas showed that Green Sandpipers were present in two estuarine 10km squares during the winters of 1981-82, 1982-82 and 1983-84.
The colour represents single birds seen a day. The UK is at the northern extremity of the winter range of this species.
