White-eyed Attila
Attila bolivianus
The white-eyed attila is 19 to 22 cm (7.5 to 8.7 in) long and weighs 40 to 45 g (1.4 to 1.6 oz). The sexes have the same plumage. Adults of the nominate subspecies have a grayish rufous-brown head. Their upperparts are mostly rufous-brown with a bright cinnamon-rufous rump and tail. Their wings are mostly rufous-brown with blackish greater coverts and primaries. Their chin is faintly grayish. Their throat and underparts are mostly cinnamon-rufous that is paler on the belly. Subspecies A. b. nattereri is overall darker than the nominate and has a crown tending to sepia. Voice: One description of the white-eyed attila's song is a "slow, rising series of about 10-15 fluted notes, which level out in the 2nd half". Another is "a slow rising series of rising whistles that usually terminates in a lower note, sounding melancholy: wur wer weer wee WEE WEE wurr".
