Aves, Charadriiformes, Scolopacidae, Calidris fuscicollis (Vieillot, 1819) (White-rumped Sandpiper): documented records for the states of Piauí and Ceará in north-eastern Brazil

The White-rumped Sandpiper, Calidris fuscicollis (Vieillot, 1819) is a small-sized shorebird (25–51 g; total length 150–170 mm) that breeds in the tundra of Alaska and northern Canada. The species is a long-distance migrant, wintering on sandy beaches, lagoons and other coastal habitats in southern South America (Hayman et al. 1986; Piersma et al. 1996). In Brazil, this species is common and very abundant in the state of Rio Grande do Sul between October–April, but with peaks in November (Harrington et al. 1986; Morrison and Ross 1989; Vooren and Chiaradia 1990).
