Gray-hooded Attila is endemic to the Atlantic forests of southeastern Brazil. This is a large long-billed species of attila. Gray-hooded Attila is named for the gray head and nape (with whitish-gray throat), which contrast with the primarily rufous body plumage; the rump and belly are paler, more cinnamon colored or ochraceous. This species overlaps, in part, with two other species of attila. In the southern part of its range, from Rio de Janeiro south to Rio Grande do Sul, Gray-hooded Attila overlaps with Rufous-tailed Attila (Attila phoenicurus); Rufous-tailed is similar, but is smaller, with a shorter bill and a rufous throat. Farther north, from Bahia south to Rio de Janeiro, Bright-rumped Attila (Attila spadiceus) also occurs; rufous morph Bright-rumped Attilas always show wing bars and a streaked breast, unlike the unmarked wings and breast of Gray-hooded Attila. Little is known about the natural history of this species. Like other species of attila, Gray-hooded Attila forages in humid forest, and is heard more often than it is seen.
