Sandpiper

Sandpipers are a large family, Scolopacidae, of waders or shorebirds. They include many species called sandpipers, as well as those called by names such as curlew and snipe. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food,More info:wiki

#10       Least Sandpiper,More info:ebird

Tiny brownish sandpiper. At all ages, most easily distinguished from other small sandpipers by darker, more brownish coloration. Juveniles are particularly bright with rusty tones on the upperparts. Also note fine-tipped bill and yellowish legs, but beware legs can be covered with dark mud and other peeps (like Semipalmated Sandpiper) can rarely show slightly greenish legs. Habitat and behavior are helpful supporting clues, too. Typically forages in a crouched posture with bent legs, picking for invertebrates in the mud. Often in small loose groups, but not in large, tight flocks like Semipalmated or Western Sandpipers. Prefers drier mud, often on the higher edges of mudflats or small patches of water in marshes. Widespread and common, especially inland. Breeds in various wetland habitats throughout Alaska and Canada. Winters from the southern U.S. to South America. Listen for high-pitched, rolling “greeep!” calls.

#7     Western Sandpiper,More info:ebird

Small sandpiper with relatively long, droopy bill (longer on females). In breeding plumage, shows rich rufous tones on shoulders, cheeks, and crown. Nonbreeding is plain pale gray above and white below. Juveniles look pale-faced and have a bright strip of rufous feathers on the upper edge of the wings. Most similar to Semipalmated Sandpiper, which averages shorter-billed and duller grayish-brown overall. Extremely difficult to distinguish in winter; note Western is somewhat larger-headed and more front-heavy. Droopy bill might recall Dunlin, but Western is smaller and paler. Breeds on high Arctic tundra in Alaska. In migration and winter, occurs in large flocks on mudflats and beaches. Much more common in western North America; uncommon to rare on the east coast. Occurs in the winter in the U.S., unlike Semipalmated Sandpiper; regularly winters as far south as Peru, rare to Chile.

#5     Solitary Sandpiper,More info:ebird

Medium-sized shorebird. Gray above and white below, with fine white speckling on wings and bold white spectacles. Note dark underwing and dark rump in flight. Smaller and shorter-legged than Lesser Yellowlegs, with duller greenish legs. Often alone, but multiple individuals may gather loosely in appropriate habitat. Tips body like Spotted Sandpiper, but less constantly and not as quick and dramatic. Breeds around ponds and marshes in the boreal forest; uses old songbird nests in trees, unlike most other shorebirds. In migration and winter, mostly seen on small bodies of water like muddy ponds, lake edges, and slow-moving streams. Extensive winter range throughout Central and South America. Listen for piercing, high-pitched “tsee-weet!” call.

#3     Meet The Smallest Sandpipers of the San Francisco Bay,More info:baynature

They’re known as peeps for their high-pitched voices. They’re the runts of the Scolopacidae, the shorebird family that includes sandpipers, yellowlegs, willets, turnstones, curlews, godwits, dowitchers, and phalaropes. The aptly named least sandpiper (Calidris minutilla) is sparrow-size and weighs about three-quarters of an ounce (equal to a dollar in quarters); the western sandpiper (C. mauri) is only a bit larger.

Those two species are by far our most common peeps. But it can be a challenge to tell them apart. Westerns tend to forage at the water’s edge, leasts on drier ground, but they frequently overlap and mixed flocks are not uncommon. “Leasts are more likely to be back in the tidal channels, in more vegetated areas,” says Point Blue Conservation Science biologist Dave Shuford. “They tend to occur in smaller flocks and are less prone to flush, more likely to freeze when a raptor goes over.” Both engage in dazzling synchronized flight, often provoked by a passing raptor.  William L. Dawson (Birds of California) describes the flight of a western sandpiper flock: “[T]hey weave and twist about, now flashing in the sunlight, now darkening to invisibility, charge and recharge, feint and flee, all as a single bird.”

Understanding and managing migratory animal populations requires knowing what’s going on with them during all stages of their annual cycle—and how those stages affect each other. The annual cycle can be especially difficult to study for species that breed in the Arctic and winter in South America. A new study from The Condor: Ornithological Applications tackles this problem for Semipalmated Sandpipers, historically one of the most widespread and numerous shorebird species of the Western Hemisphere, whose populations in some areas have undergone mysterious declines in recent years.
