ウスグロタイヨウチョウ Cinnyris fuscus

A small sunbird. The male is dark overall, with a pale lower belly and orange tufts at the shoulder that are sometimes hidden. The female is plain gray-brown with a paler lower belly. Singles and pairs prefer arid scrub and savanna, feeding on insects and nectar. The species is nomadic and can irrupt in large numbers into areas where it is normally irregular, often on the fringes of its range. The female Dusky Sunbird has paler underparts than the similar female Southern Double-collared Sunbird.
