especially on the median pair, tipped with grayish or bufFy white, 

 subterminally obscurely and broadly banded with chaetura drab to 

 chaetura black, and barred (9 or 10 bars) narrowly ■s\ath the same, and 

 whitish basally; the barring usually not extending to the outer webs 

 of the outermost pair of rectrices; the gray of these feathers often with 

 a dull silvery sheen; lores, chin, and middle of throat white; a very 

 broad pectoral area covering the entire breast pinkish cinnamon to 

 light russet, the feathers with narrow dusky shaft streaks, the upper 

 part of this area often washed with darker brown; rest of underparts 

 including under wing coverts, under tail coverts, and thighs white or 

 buffy white, the feathers of the sides of the upper abdomen incom- 

 pletely barred with snuff brown, sayal brov/n, or tawny-olive; some- 

 times almost immaculate; the under wing coverts with a few small 

 fuscous bars; iris dark Vandyke brown; bill blackish; cere pale greenish 

 yellow; feet wax yellow. 



Adult female. — Pale phase: Similar to the male, but with relatively 

 less cinnamon or tawny edgings on the feathers of the upperparts; 

 the forehead buffy mixed with dull fuscous, or wholly fuscous like the 

 crown; the pectoral area darker, less rufous — Saccardo's umber to 

 sepia; soft parts as in male. 



Adult. — Rufous phase (sexes ahke in color) : Entirely similar to the 

 pale phase, but with the entire abdomen, sides, flanks, thighs, and 

 under tail coverts heavily washed with pale sayal brown to hazel and 

 obscurely but narrowly and abundantly barred with russet; under 

 wing coverts pale tawny marked with sayal brown and fuscous; 

 forehead as in female of pale phase, and concealed nape patch buffy 

 and reduced in size. 



Adult. — Black phase (sexes alike in color) : Remiges and rectrices 

 as in pale phase; all the rest of the body and head, except the under 

 tail coverts, fuscous black to chaetura black, the feathers of the upper 

 back and the upper wing coverts with slightly paler edges; under tail 

 coverts buffy whitish heavily marked and barred with sayal brown to 

 fuscous; the dusky bars on the rectrices broader than in the pale phase; 

 soft parts as in pale phase. ^° 



Immature. — There is no true immature plumage; the juvenal 

 plumage appears to be retained through the fu-st \^'^nter (that is, 

 there is no autumnal postjuvenal molt) and the transition to the adult 

 plumage seems to be rather slow and irregular (judged from the num- 

 ber of intermediate specimens seen) . 



*• Individuals exhibiting every stage of intermediacy betvi'een all three phases 

 may be found in any long series. Thus, while there are numerous specimens that 

 do not match any of the above descriptions in every respect, the three phases are 

 as given here.
