Sandpipers and Allies
Actitis macularius
The Spotted Sandpiper is a widespread and distinctive shorebird found across North America. Known for its unique teetering motion, this species is often encountered individually along various aquatic habitats. Its appearance changes notably between breeding and non-breeding seasons, making it a memorable bird for curious observers.
Typical adult measurements.
Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Adults display prominent, round black spots on a white breast and belly, with a brown back.
Spots are absent, showing a plain white underside and grayish-brown upperparts. A white wedge extends onto the shoulder.
A thin, straight bill that is orange with a dark tip during breeding season, becoming yellow with a dark tip in winter.
Short, yellowish or pinkish legs are characteristic in all plumages.
02 / A place in the world
This species favors the edges of freshwater bodies such as lakes, ponds, rivers, and streams, in both open and wooded areas. During migration and winter, it can also be found on coastal mudflats, beaches, and breakwaters.
Spotted Sandpipers breed across most of North America, from the Aleutian Islands and Alaska eastward through Canada and southward into the United States. They winter from the southern U.S. and Caribbean down to southern South America.
Most populations are fully migratory, traveling individually or in small groups during both day and night. Populations along the western coast of the United States and in parts of California may reside year-round.
03 / Listen a little closer
Their calls are often described as a clear, piping "peet-weet" or "weet-weet."
04 / The life behind the feathers
Primarily carnivorous, their diet consists of a wide array of small invertebrates, including various insects like midges, flies, grasshoppers, beetles, and worms, as well as crustaceans, mollusks, and spiders.
They forage on the ground, capturing prey by thrusting their head forward, pecking, or hopping to catch flying insects. They also pick insects off vegetation.
Nests are shallow depressions on the ground, lined with grass and moss, typically near freshwater in vegetated areas. Females may lay clutches for multiple males, with males primarily incubating eggs and caring for young.
Known for its distinctive teetering or bobbing motion of the rear body, which speeds up when nervous. Females establish and defend breeding territories, often arriving before males.
One more reason to pay attention
Female Spotted Sandpipers exhibit polyandry, mating with multiple males who then each care for a clutch of eggs.
The characteristic teetering motion of this sandpiper is present even in newly hatched chicks, though its exact function remains unknown.
The Spotted Sandpiper is the most widespread breeding sandpiper in North America.
