It is native to the nations of North America and many island nations and has been seen in various countries throughout Europe. This bird prefers wetlands and neritic or coastal marine ecosystems. The global population of this bird is estimated to be 1,100,000 to 2,200,000 individuals and it does not appear to meet population decline criteria that would necessitate inclusion on the IUCN Red List.
