s, especially during brief stops on migration. In summer, breeds on rather barren, rocky tundra above treeline in northern mountains.
Nest: Site is on ground, in natural depression in rocky surface of high, dry ridge, in area surrounded by very low ground cover. Nest (probably built by both sexes) is simple lining of dead leaves, lichens, and moss added to nest depression.
Eggs: 4. Buff, spotted with dark reddish brown. Incubation is by both sexes, incubation period not well known.
Young: Downy young leave nest soon after hatching. Both parents tend young, but young find all their own food. Development of the chicks and age at first flight not well known.
In summer on tundra, feeds mostly on insects; also spiders, snails, seeds. On coast (where it spends most of year), feeds on mollusks, such as mussels, limpets, and snails, as well as barnacles and other crustaceans, other small invertebrates.
Behavior: Major feeding method on coast involves removing barnacles, limpets, and
young mussels from rocks with a quick sideways jerk of the head; the Surfbird’s thick bill is adapted for this behavior. Also picks up snails and insects from ground or rocks, sometimes probes in mud.
southern South America. Migration:
Limited breeding range, but wintering range stretches from Alaska to Chile. Some can be found on wintering range at least from late July to early May. On our southern Pacific Coast, the only noticeable migration peak occurs in spring, mainly April.
