Spotted sandpiper Description

Spotted sandpipers are medium-sized sandpipers. The crown, nape, back, and wings of spotted sandpipers are brown to olive-gray, while the face, neck, chest, and belly are dazzling white. Their common name refers to the large black dots that cover their white undersides. In comparison to males, females have larger markings that reach lower on the belly. When spotted sandpipers fly, they exhibit a white wing stripe and a plain rump and tail.

Size

These birds have a length of 7.5 in (19 cm) and a weight of 64 g (2.25 oz). Their wings could range from 13-14 in (33-36 cm).

Feeding

By probing their bills into sand and mud, the Spotted Sandpiper feeds mostly on insects such as midges, flies, grasshoppers, beetles, worms, snails, and small crustaceans. Additionally, they will consume small and dead fish.

Habitat

Spotted sandpipers breed in a variety of habitats from sea level to 4,700 m in elevation. Females defend a breeding territory that often comprises a shoreline (of a stream or lake, for example), a semi-open region for nesting, and areas of dense vegetation.

Behavior

The spotted sandpiper is a diurnal bird. They can sleep at any time of the day or night, but prefer to do so when it is dark. During the day, spotted sandpipers spend time grooming, rubbing their heads, stretching, and bathing. Spotted sandpipers are completely migratory, save for populations that nest and winter along the west coast of the United States and in select parts of California. The spotted sandpiper migrates both day and night. In contrast to the majority of shorebirds, they move alone or in small groups.
