Fanti Sawwing

Fanti Sawwing

Psalidoprocne obscura

An elegant sooty-brown swallow with a distinctive long and deeply forked tail. Plumage has a greenish gloss if seen well. Female and juvenile have shorter tails, and the latter is brownish. Resident in some areas; in others, occurs only in the breeding season. Pairs prefer foraging over clearings and the edges of evergreen forest, open woodland, and cultivation, usually near water. Not very vocal, but emits faint squeaky notes and trills. The only other sawwing in Fanti’s range is Square-tailed, which has a much shorter, square-ended tail. 

Tibetan Sand-Plover

Tibetan Sand-Plover

Anarhynchus atrifrons

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.

Long-tailed Potoo

Long-tailed Potoo

Nyctibius aethereus

Large potoo with a long graduated tail. Mostly rusty brown with streaked underparts, a conspicuous pale shoulder patch, and a whitish moustache. Occurs from the lower to the upper levels of humid forests. The song is an undulating “waa-OO-uh,” usually sung on moonlit nights.
