Spotted Sandpiper
Spotted Sandpiper
Actitis macularius
At a Glance
Most sandpipers nest only in the far north, but the little 'Spotty' is common in summer over much of North America. As it walks on the shores of streams, ponds, and marshes, it bobs the rear half of its body up and down in an odd teetering motion. When startled, it skims away low over the water, with rapid bursts of shallow wingbeats and short, stiff-winged glides. Even where it is common, it is seldom seen in flocks.

Behavior
Eggs
4, sometimes 3, rarely 5. Buff, blotched with brown. Incubation is usually by male only, 20-24 days; female may help incubate final clutch of the season.
Young
Downy young leave nest soon after hatching. Young feed themselves, are usually tended by male only. Age at first flight about 17-21 days.
Feeding Behavior
Forages in a variety of ways. Picks up items from surface of ground or water; snatches flying insects out of the air; plucks small items from shallow water. On open flats, may crouch low, stalk slowly, then dash forward to catch insects or small crabs.
Diet
Insects, crustaceans, other invertebrates. Feeds on wide variety of insects, also earthworms, crabs, crayfish, small mollusks, small fish, sometimes bits of carrion.
Nesting
Has a complicated mating system. Females are slightly larger and much more aggressive, actively defending breeding territory with displays in flight and on ground. At least in some parts of range, one female may mate with up to five males during a season; each time, female lays a clutch of eggs, leaving male to incubate the eggs and care for the young. Nest site is near water or some distance away, on ground under shrubs or weeds, next to fallen log, etc. Nest (built by both sexes) is shallow depression lined with grass, moss, sometimes feathers.
Climate Vulnerability
Conservation Status
Numbers are thought to have declined in many parts of range during recent decades, probably owing to loss of habitat. However, still widespread and common.
