Angola Greenbul

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.

Warm brown above and pale below; strong dark eyestripe contrasts with white eyebrow. Smallish reed warbler with long and strongly rounded tail, short bill with dark tip, and short primary projection. Difficult to separate visually from other small Acrocephalus warblers, especially Blunt-winged Warbler; note Paddyfield’s more prominent pale eyebrow which strengthens behind the eye, as well as longer-winged appearance. Also compare with Iduna warblers. Breeds in extensive reed beds; in nonbreeding season found in marshes, but also more scrubby areas. Distinctive, melodious song.

Both sexes look like a dark-colored female Mallard. Bill of male is dull yellowish; bill of female is mottled orange and black, like a typical Mallard. In flight, bright white underwings contrast with dark body. Note distinct white stripe in front of iridescent panel on upperwing, compare to Mottled Duck (limited range overlap). Usually in pairs or small flocks; wary in most areas, but in some city parks and urban settings has become fairly tame. In some areas of sw. US, hybridizes with Mallard, producing birds with variably intermediate features.
