Similar species
Almost identical to Long-billed Dowitcher. Bill lengths overlap with females having longer bills than males. Distinguished in breeding plumage by whitish belly and spotted rather than barred sides of breast. Juveniles distinguished by heavily patterned upperparts, particularly tertials with internal markings. In winter plumage, not safely distinguished except by voice. Typical call a mellow whistled "tu-tu-tu." Long-billed is more vocal often keeping contact while feeding. Flight call a higher pitched squeaky "keeek" recalling Sanderling.
Distribution
Breeds in Alaska and Canada; winters from southern U.S. to central South America.
Taxonomy
Subspecies
There are 3 subspecies1:
- L. g. caurinus - "Pacific":
- L. g. hendersoni - "Prairie":
- L. g. griseus - "Atlantic":
Habitat
Bogs, tidal marshes, mudflats or forest clearings.
Behaviour
Breeding
Ground-nesters, usually close to water. The nest is a shallow depression in grass or moss, lined with fine grass, twigs and leaves. The clutch consists of 3-4, olive-buff to brown eggs which are incubated by both adults for 21 days.
Diet
The diet includes insects, molluscs, crustaceans and marine worms, and also eat some plant material.
