Least Sandpiper

Calidris minutilla

The Least Sandpiper, *Calidris minutilla*, holds the distinction of being the smallest shorebird in the world, a true "peep" among its kind. Measuring a mere 13-15 cm (5-6 inches) in length with a wingspan of 27-30 cm (10.5-12 inches) and weighing just 19-30 grams, its diminutive size is often its first identification clue. Distinctive field marks include its yellowish or olive-yellow legs, a finely tipped, slightly decurved black bill, and a characteristically hunched posture. In breeding pl...

Habitat

Primarily found in open, wet habitats, ranging from coastal mudflats and salt marshes to tundra pools and flooded fields. Prefers shallow waters and muddy substrates for foraging, often near sea level but can be found at moderate elevations during migration.

Diet

Feeds predominantly on small invertebrates, including insects (larvae, beetles, flies), small crustaceans, mollusks, and marine worms, gleaned from mud and shallow water. Occasionally consumes seeds and detritus.

Least Sandpipers are primarily diurnal, actively foraging throughout the day, though they may also feed during moonlit nights or at dawn/dusk, and roost communally in sheltered spots. Their foraging strategy involves a rapid, almost frantic, pecking and probing into shallow water and mud, using t...

Range

The Least Sandpiper boasts an extensive breeding range across the high Arctic and subarctic regions of North America, encompassing Alaska, the Canadian Arctic Archipelago, and mainland Canada south to Newfoundland. During the non-breeding season, these hardy migrants journey south, wintering exte...
