White-headed Brushfinch

The white-headed brushfinch (Atlapetes albiceps) is a species of bird in the family Passerellidae, the New World sparrows. It is found in Ecuador and Peru. == Taxonomy and systematics == The white-headed brushfinch was formally described in 1884 with the binomial Buarremon albiceps. In the early twentieth century genus Buarremon was merged into Atlapetes. The white-headed brushfinch is monotypic. However, some authors have suggested that the pale-headed brushfinch (A. palidiceps) should be a subspecies of it but they are not closely related. == Description == The white-headed brushfinch is 16 to 17 cm (6.3 to 6.7 in) long. It weighs 35 to 39 g (1.2 to 1.4 oz). The sexes have the same plumage. Adults have a black crown and nape; the rest of their head including the forecrown is white. Their upperparts are slate gray and their wings and tail are slightly more blackish. Their primaries have white bases that show as a patch on the closed wing. A very thin black line separates their ear coverts from their throat. Their breast and flanks are grayish and their belly and vent white. They have a brown iris, a black bill, and gray legs and feet. == Distribution and habitat…
