Calidris alba – PIBYDD Y TYWOD – Passage migrant. Recorded in all months
The BTO winter atlas showed that Sanderlings were present in one estuarine and a few coastal 10km squares during the winters of 1981-82, 1982-82 and 1983-84.
The blue colour in each 10km square represents up to 19 birds.
The distribution coincides largely with sandy shores.
