- Calidris minutilla
13–15 cm (5-6 in)
In most of its range, it is the only peep with yellow legs, but note distinction from Long-toed Stint below. Least Sandpiper has short thin dark bill, brown with dark brown streaks on top and white underneath. Light line above the eye and a dark crown.
Semipalmated Sandpiper is plump compact looking, more white to throat, has slightly heavier black legs, and semipalmations between toes.
Western Sandpiper is lanky looking, has black legs, and semipalmations between toes. In Breeding plumage is heavily spotted on belly and is grayish withrufous on crown, auriculars, and scapulars.
Long-toed Stint has a different lore pattern with a white teardrop shaped extension forward of the supercilium which loops down in front of the eye, ending before the bill. Long-toed also has a vertical dark mark in front of the eye and a thin sub-loral loop which together form a sideways "J" mark in all plumages. Least has a straight lore stripe. In juvenile plumage Least Sandpiper has buffy fringes to median coverts while Long-toed has these feathers white edged (lower scapulars are white tipped on both). Split supercilium often claimed as a feature of Long-toed Stint is not reliable.
Formerly placed in genus Erolia. In past, sometimes considered conspecific with Long-toed Stint.
Tundra or in bogs. In migration found at mud flats, beachs, sod farms, etc.
Often in crouched position with knees very bent, feet planted forward (so far many times that they can appear to be feeding between their toes) and with belly much closer to ground than other peeps2. Usually found on shore instead of wading.
The 4 eggs are laid in a shallow scrape on the ground, lined with grass and most. Both parents incubate.
These birds forage on mudflats; their diet includes small crustaceans, insects and snails.
Typical flight call is a high-pitched slightly rolled kree-eeet. Other calls and songs during breeding season.
Migratory. Moves in broad front over interior North America to Southern USA, Greater Antilles, Gulf of Mexico, Middle America and northern South America.
