The Caquetá seedeater (''Sporophila murallae'') is a passerine bird from the western Amazon Basin in south-eastern Colombia, eastern Ecuador, north-eastern Peru and far western Brazil (western Acre and Amazonas only). The status in south-eastern Peru is unclear. Together with the mainly Central American ''S. corvina'', it was formerly considered a subspecies of ''S. americana'', in which case the common name for the combined species was variable seedeater. Following the split, this common name is now restricted to ''S. corvina''. ==Description== It has a total length of approximately . Adult males have a relatively heavy black bill. The upperparts are black, except for a greyish rump (actually white finely streaked black, but only visible up-close), a white wing-bars and a small white wing-speculum. The underparts are white, except for an irregular black chest-band (often inconplete) and greyish mottling to the flanks. Some individuals show a black malar. The far duller female has a brownish bill, dull buffy-olive upperparts and pale olive-ochre underparts. Juveniles resemble adult females.
