The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Siberia to Canada; in Britain and Ireland 53,000 in winter.
Cornwall: winter visitor and passage migrant to most major estuaries, with a few summering (midwinter counts total some 500 birds). Chief sites are Camel estuary and the Lynher/St. John' s Lake (both holding 150 to 200 regularly, but numbers fluctuate). Isles of Scilly: small numbers on passage; few overwinter.
Habitat & Ecology
Muddy and sandy estuaries, locally on coastal reefs and bays. Peak numbers do not
arrive until mid winter.
Most sites are SSSI. Protected under Annexe 11/2 of the European Union Conservation of Wild Birds Directive. Listed (long list) as a globally threatened/declining species (BSGR, 1995).
