Fairly common but declining large wader (shorebird) of varied open habitats. Breeds mainly in grasslands, from coastal marshes to upland moors; winters mainly in coastal lowlands, especially mudflats and adjacent marshes. Note large size, overall brown plumage, and long, decurved bill (appreciably shorter on juvenile). In flight shows white back patch, mostly white underwings. Common call an onomatopoeic "coor-lee." Compare to smaller Whimbrel, which has head stripes, a piping whistled call, and winters mainly in Africa.
