Galapagos Shearwater

Puffinus subalaris

Very small black-and-white shearwater of warm tropical waters. Can be seen from shore off the coast of Oaxaca. Often in flocks, sometimes of thousands, resting on the water and in feeding flocks with Brown Boobies, Black Terns, and other shearwaters. Flight quick and low, with hurried wingbeats and only short glides. Smaller and shorter-winged than Black-vented Shearwater and rare Townsend’s Shearwater. Black-vented has messier brown colors on the side of its head, without distinct dark cap of Galapagos. Townsend’s is blacker above with white patches (saddlebags) at sides of rump.

Identification

The Galápagos shearwater has dark brown upperparts, undertail and underwing flight feathers, the rest of the underparts plumage being white. It sometimes has a dark collar. Both sexes are alike, as are the young after fledging.<p>It is a slender-bodied shearwater, about 29–31 cm long, with a wingspan of around 63 cm and weighs 123-225 g. The species closely resembles the tropical shearwater, although the latter is typically blacker and has a longer tail.

Thicket Antpitta

Thicket Antpitta

Myrmothera dives

Secretive and very difficult to see. Distinctive antpitta shape: very plump with hardly any tail, very long sturdy legs. Distinguished from other antpittas by rich rufous flanks with darker streaking on breast. Hops on the ground in dense forest, edges, and tangles; sometimes perches off the ground to sing (but still always concealed). Much more easily heard than seen; listen for its fast rising series of whistles.

Pectoral Sandpiper

Pectoral Sandpiper

Calidris melanotos

Beefy, medium-sized sandpiper. Brown-toned overall with yellowish legs. Slightly curved bill pale at base. Look for dense breast streaking with abrupt border at white belly. Males are much larger than females, and have a large air sac in the throat which they inflate during breeding display. Plumage and yellow legs might recall Least Sandpiper, but Pectoral is much larger and looks longer-necked. Compare with Sharp-tailed Sandpiper, which is brighter overall and has a more distinct dark cap. Breeds on tundra in the high Arctic. Winters mainly in southern South America, but small numbers also winter in Southeast Asia, Australia, and New Zealand. Typically seen in small flocks in muddy marshes or wet grassy habitats, sometimes mixed with other shorebirds. Much less common on open mudflats or beaches. Listen for low, trilled calls.

James's Flamingo

James's Flamingo

Phoenicoparrus jamesi

Rather local; found at salt lakes and bogs in the high Andes. Associates readily with Chilean and Andean Flamingos, although each species often stays slightly apart within mixed groups. James’s is the smallest New World flamingo best identified by its relatively short, stubby bill, which is yellow with a black tip. Adult and older immature have distinctive red legs and feet (can be whitish when caked with dried salt). Immature is whitish overall, like other immature flamingos.
