Black and White TanagerThe Black-and-white Tanager (Conothraupis speculigera) is a South American tanager that occurs naturally Ecuador, Peru and the Brazilian state of Acre. It inhabits scrub, woodland and forest borders at elevation of 100-1800 m. (330-5900 ft).

This species is generally uncommon to rare. The only other member of its genus is the recently rediscovered Cone-billed Tanager.

These birds are usually seen singly or in pairs, but occasionally also occur in flocks of up to 50 individuals.

The male is mostly black with a grey rump, white underparts and a white wing-speculum (= distinctive wing patch) .

The female is olive with faintly mottled, yellow-tinged underparts.
