The Dunlin (Calidris alpina) is a small wader, sometimes separated with the other "stints" in Erolia. It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in northern Europe and Asia are long-distance migrants, wintering south to Africa, southeast Asia and the Middle East. Birds that breed in Alaska and the Canadian Arctic migrate short distances to the Pacific and Atlantic coasts of North America, although those nesting in Northern Alaska overwinter in... less ↑

The Stilt Sandpiper (Calidris himantopus) or Micropalama himantopus, is a small shorebird; it bears some resemblance to the smaller calidrid sandpipers or "stints". DNA sequence information is incapable of determining whether it should be placed in Calidris or in the monotypic genus Micropalama. It appears most closely allied with the Curlew Sandpiper, which is another aberrant species only tentatively placed in Calidris and could conceivably separated with it in Erolia. less ↑

The Pectoral Sandpiper (Calidris melanotos) is a small, migratory wader that breeds in North America and Asia, wintering in South America and Oceania. It eats small invertebrates. Its nest, a hole scraped in the ground and with a thick lining, is deep enough to protect its four eggs from the cool breezes of its breeding grounds. The pectoral sandpiper is 21 cm long, with a wingspan of 46 cm. less ↑

The Short-billed Dowitcher (Limnodromus griseus) like its congener the Long-billed Dowitcher, is a medium-sized, stocky, long-billed shorebird in the family Scolopacidae. It is an inhabitant of North America, Central America, and northern South America. It is strongly migratory; it completely vacates in breeding areas during the snow-bound months. This species favors a variety of habitats including tundra in the north to ponds and mudflats in the south. It feeds on invertebrates often by rapidly probing its... less ↑

The Wandering Tattler, Tringa incana (formerly Heteroscelus incanus: Pereira & Baker, 2005; Banks et al., 2006), is a medium-sized wading bird. It is similar in appearance to the closely related Gray-tailed Tattler, T. brevipes. The tattlers are unique among the species of Tringa for having unpatterned, greyish wings and backs, and a scaly breast pattern extending more or less onto the belly in breeding plumage, in which both also have a rather prominent supercilium. less ↑

The Greater Yellowlegs (Tringa melanoleuca) is a large North American shorebird, similar in appearance to the smaller Lesser Yellowlegs. Its closest relative, however, is the Greenshank, which together with the Spotted Redshank form a close-knit group. Among them, these three species show all the basic leg and foot colors found in the shanks, demonstrating that this character is paraphyletic (Pereira & Baker, 2005). They are also the largest shanks apart from the Willet, which is altogether... less ↑

The Willet (Tringa semipalmata), formerly in the monotypic genus Catoptrophorus as Catoptrophorus semipalmatus, is a large shorebird in the sandpiper family. It is a good-sized and stout scolopacid, the largest of the shanks. Its closest relative is the Lesser Yellowlegs, a much smaller bird with a very different appearance apart from the fine, clear, and dense pattern of the neck, which both species show in breeding plumage. less ↑

Wilson's Snipe (Gallinago delicata) is a small, stocky shorebird. This species was considered to be a subspecies of the Common Snipe (G. gallinago) until 2003 when it was given its own species status, though this is not recognized by all taxonomic authorities. Wilson's Snipe differs from the latter species in having a narrower white trailing edge to the wings, and eight pairs of tail feathers instead of the typical seven of the Common Snipe. Its common... less ↑

The Ruddy Turnstone (Arenaria interpres) is a small wading bird, one of two species of turnstone in the genus Arenaria. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. It is a highly migratory bird, breeding in northern parts of Eurasia and North America and flying south to winter on coastlines almost worldwide. It is the only species of turnstone in much of its range and... less ↑

The Wilson's Phalarope (Phalaropus tricolor) is a small wader. This bird, the largest of the phalaropes, breeds in the prairies of North America in western Canada and the western United States. It is migratory, wintering in inland salt lakes near the Andes in Argentina. They are passage migrants through Central America around March/April and again during September/October. The species is a rare vagrant to western Europe. less ↑
