on the head than on the back ; remiges and rectrices with a grayish 

 (silvery in the remiges) tinge and barred with fuscous brown; 

 underparts whitish, the chin, throat, and breast with large tear- 

 shaped splotches of pale mummy brown, the thighs tawny rufous. 



B. Upper parts similar to A but with the general color darker and 

 all the feathers (except those of the head) edged with rufous brown; 

 remiges with almost none of the silvery gray tinge, the outer three 

 very dark terminally and unhanded, the rest dark grayish brown 

 barred with fuscous ; the rectrices as in A but washed with chestnut, 

 all the tail feathers tipped with chestnut; underparts tawny cinna- 

 mon; chin and throat narrowly streaked with blackish, the breast 

 and forward part of abdomen with large dark-brown blotches. 



This plumage seems to be retained until the following year. When 

 the bird is nearly one year old it undergoes a postjuvenal molt. I 

 can not be quite certain if this molt is complete or not, but it seems 

 to involve only the feathers of the body and head and not the wings 

 and tail. 



3. The immature plumage is as follows : 



A. Similar to the juvenal plumage but darker above, underparts 

 less spotted except on the chin and throat; thighs whitish, not tawny 

 rufous, tail still barred. 



B. Similar to the juvenal plumage of this phase but darker. Gen- 

 eral color sootv brown above and below. I have seen no specimens 

 of this plumage but feel that it (plumage No. 3 of Claude Grant's 

 account) is the immature plumage of the dark phase, not the juvenal 

 plumage as was indicated by Grant. The juvenal plumage that I 

 have described above is taken from a bird taken from a nest and, 

 obviously, can be no other than the first pennaceous feathering. 



4. The subadult plumage is acquired by what seems to be a com- 

 plete molt. 



A. Upper parts varying from fuscous black to black, the remiges 

 black terminally, otherwise (with the exception of the outermost 

 pair) grayish, barred narrowly with brownish, the innermost sec- 

 ondaries almost whitish barred with earth-brown and broadly tipped 

 with fuscous brown ; tail and upper tail coverts bright chestnut. The 

 rectrices vary in that some have a narrow subterminal blackish band, 

 others a blackish spot on the outer tip of each vane, while still 

 others have no blackish at all. Occasionally the outer pair have 

 several narrow fuscous bars. The central pair of rectrices are the 

 first to grow in, and the tail molt is centrifugal. Underparts Avhite, 

 the chin and throat largely blackish; under wing coverts white, 

 broadly tipped with black. 



B. Upper parts varying from dark fuscous to black; wings as in 

 corresponding plumage of the light phase ; upper tail coverts bright
