Range and Habitat
Curlew Sandpiper: Passage visitor to nearly the entire coast of England, as well as the east coasts of Scotland and Ireland. Most often seen in early autumn as birds head from Siberia to winter grounds in Africa. Marshes, lagoons, and mudflats are all areas where birds can be seen.
Breeding and Nesting
Curlew Sandpiper: Nests are built in open tundra, or near marshes, on islands and along coastlines. Prefers wet depressions, bogs, and melting snow on southward-facing slopes. Nest is a cup. Predation by Arctic foxes affects breeding success, especially when there are few lemmings for foxes to eat.
Foraging and Feeding
Curlew Sandpiper: Forages mostly in intertidal mud and shallow marshes by pecking and probing in a"stitching" motion. Finds insects and other small invertebrates mostly by sight. In winter eats mollusks and crustaceans; occasionally insects, seeds.
Vocalisation
Curlew Sandpiper: Call is a pleasant, liquid "chirrup" or "chirrip" in flight, or a "wick-wick-wick" in alarm. Male sings while flying on breeding grounds.
Similar Species
