 feather broadly edged with light yellowish olive, this color brightest 

 and yellowest on the remiges and their greater and median upper 

 coverts, dullest, most sooty on the interscapulars, the edgings on the 

 back rump and upper tail-coverts broad enough to give those areas 

 an appearance of almost solid yellowish olive; ^^ two median pairs 

 of rectrices dark fuscous to fuscous black; the more lateral ones white 

 with dusky olive brown latero terminal blotches on their outer webs; 

 all but the outermost pair with some olive brown basally as well

 pale 3'-ellowish, each feather with a median streak of didl dusky olive 

 brown to chaetura drab; breast and upper abdomen similar but more 

 strongly washed with pale olive buff, and with the dark median 

 streaks frequently bifurcatmg subterminally to become edgings and 

 tippings of the feathers enclosing a rounded subterminal whitish or 

 pale buffy area; sides and flanks similar but with the dusky areas 

 paler, grayer, and less distinct — light grayish olive; middle of upper 

 abdomen and lower abdomen, vent, and under tail-coverts pale olive 

 buff to almost whitish, especially posteriorly; thighs white; under

 base 12-13.5, tarsus 15-17.3. Weight in grams: 49, 50, 60.5. 



Adult female: Similar to the male, but smaller, with the dusky 

 markings on the chin, throat, and breast averaging paler and sparser,

Juvenal (sexes alike): Similar to the adult female, but sometimes 

 more yellowish, and wnth the rectrices and the remiges narrower, more 

 pointed terminally, often with the throat and breast spots darker, 

 more conspicuous than in adults. 



Natal down: None. 



The subspecies virescens resembles the nominate race in everything 

 but size. It is considerably smaller, although the two overlap. 



21 Zedlitz (1915, p. 8) states that frequently the upperparts are wholh' without 

 any greenish tone. I have not seen any specimens that had no greenish wash or, 

 at least, edgings.
