Asemospiza fuliginosa
The Sooty Grassquit (Asemospiza fuliginosa) is a petite Neotropical passerine, recently reclassified from the genus *Sporophila* to *Asemospiza*, reflecting its distinct evolutionary path. Males are uniformly sooty black with a subtle glossy sheen, measuring approximately 9.5-10.5 cm (3.7-4.1 in) in length and weighing around 7-10 g (0.25-0.35 oz), featuring a small, dark conical bill and dark legs. Females are notably duller, exhibiting an olive-brown coloration above and a paler buffy-gray ...
Primarily found in open, bushy habitats, forest edges, clearings, secondary growth, and cultivated areas, typically at low to moderate elevations up to 1,500 meters (4,900 feet).
Mainly consumes small grass seeds and seeds from other herbaceous plants, supplementing with small insects, foraging by gleaning directly from low vegetation.
Sooty Grassquits are diurnal and forage actively during daylight hours, often perching on low vegetation, fence wires, or exposed branches. They are primarily granivorous, deftly gleaning small seeds from grass heads, herbaceous plants, and low shrubs, but will also supplement their diet with sma...
The Sooty Grassquit has a broad distribution across northern and central South America, extending from eastern Colombia and Venezuela through the Guianas (Guyana, Suriname, French Guiana) and southwards into much of Brazil, eastern Bolivia, and Paraguay, with its southernmost reach into northern ...
Least Concern
- The Sooty Grassquit was recently reclassified from the genus *Sporophila* to *Asemospiza*, a move supported by genetic studies showing it is distinct from true *Sporophila* seedeaters. - Its dull, uniform plumage in males belies a surprisingly complex and sibilant song often described as "insec...
