Grey-eyed Greenlet

The grey-eyed greenlet (Hylophilus amaurocephalus) is a species of bird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found in Brazil and possibly Bolivia. == Taxonomy and systematics == The grey-eyed greenlet was originally described in 1835 as Sylvia amaurocephala, mistakenly placing it among what were then the "Old World warblers". For much of the twentieth century it was treated as a subspecies of the rufous-crowned greenlet (Hyophilus poicilotis) but by the 1990s was generally recognized as a full species. The grey-eyed greenlet is monotypic. == Description == The grey-eyed greenlet is 12.5 to 13 cm (4.9 to 5.1 in) long. The sexes have the same plumage.

Their nape and upper back are dull gray-brown and their lower back, shoulders, and rump are green-tinged gray-brown. Their wings are gray-brown with thin greenish edges on the outer webs of the primaries and secondaries. Their tail is gray-green with brighter edges on the feathers' outer webs. Their chin is dull whitish, their throat dull grayish, their flanks yellowish, and the rest of their underparts brownish…
