Maxwell's Black Weaver

A subtly colored member of the swallow family. Dark brown on the back with paler underparts. The forked tail has white spots, though these are not always easy to see. The “red throat” amounts to a slight pinkish tinge. Nests in canyons, escarpments, gorges, and on human structures. Often seen in pairs or small groups. At a distance, can be confused with “Riparia” martins; look for Pale Crag-Martin’s white tail patches. Separation from Southern Crag-Martin may be tricky, but there is little overlap in range.

Striking small cuckoo endemic to the Tanimbar, and Kai and Tayando Islands (where rare) of the southeastern Moluccas. Male is dark iridescent green above and white below, with a bright red patch of bare facial skin around each eye, and a large white wing patch. Female is similarly patterned but duller. Usually observed in thicker vegetation at the edges of dense forest or in regenerating growth. Has two primary vocalizations: a fast, slightly descending trill, and a short series of high-pitched piping notes that trail off.

Medium-sized plover with a pale throat, brown back, and white belly. Breeding adults have a black mask and a bright orange chest and neck; males average brighter than females. Non-breeding and immature birds are brownish above and white below, with a variable white forehead and eyebrow. Compare with slightly larger Greater Sand-Plover; Tibetan is proportionally smaller-headed and darker-legged, and its shorter bill has a slight bulge at the tip. Smaller Kentish Plover can be similar in non-breeding plumage; Tibetan is taller and longer-legged, without Kentish’s strong white neck band. Very difficult to distinguish from Siberian Sand-Plover, especially nonbreeding and immature birds, though identification can often be presumed by range. In breeding plumage, note the more extensive black mask of Tibetan, typically lacking the white spot on the forehead of Siberian. In nonbreeding plumage, look for a generally broken breast band and clean white flanks in Tibetan. In areas of overlap many birds best left unidentified. Breeds on margins of high-elevation lakes and rivers in China and Mongolia; winters on coastal mudflats, beaches, and inland lakes from Africa to Indonesia.
