The Black-and-white Tanager (''Conothraupis speculigera'') is a Tanager found in Ecuador , Peru and the Brazil ian state of Acre . It is found in scrub, woodland and forest borders at elevation of 100-1800 m. (330-5900 ft). It is generally uncommon to rare. The only other member of its Genus is the recently rediscovered Cone-billed Tanager .

It has a total length of 16 cm. (6½ in) and weighs 23-28 g. (0,8-1 oz). The male is black with a grey rump, white underparts and a white Wing-speculum . It is longer-billed than the superficially similar Black-and-white Seedeater and lacks the black flanks and chalk-white bill of the related Cone-billed Tanager . The female is Olive with faintly mottled, yellow-tinged underparts. Both sexes have a reddish Iris and a greyish bill. The males' song is distinctive, Blackbird -like, loud and ringing.

In the northern part of its range it breeds during the rainy-season, after which it disperses. The 2-3 brown-blotched pale blue eggs are placed in a low, untidy nest (Greeney et al, 2006). It is usually seen singly or in pairs, but has been seen in flocks of up to 50 individuals. It eats insects and seeds.
