Caqueta Seedeater

The Caqueta 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.


It has a total length of approxomately 11 cm (4 in). Adult males have a relatively heavy black bill. The upperparts are black, except for a greyish rump , 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.


Found in humid open or semi-open grassy areas and shrub; especially along edges of rivers or lakes. Usually seen in pairs or small flocks. As other Sporophila seedeaters, it mainly feeds on seeds, but has also been recorded feeding on stems, leaves and fruits (e.g. Cecropia).

It was only recently accepted as a species distinct from S. corvina and S. murallae by the South American Classification Committee, and has therefore not been rated by BirdLife International. It is fairly common throughout a large part of its range, and is likely to benefit from the widespread forest-clearance within its range. Overall, it is unlikely to be threatened at this point, but the capture for the wild bird trade could present a problem in the future (as is known from several other Sporophila seedeaters).
