Young. Above brown ; the dorsal feathers more or less margined 

 and barred with rufous ; the head streaked with deep ochre, of which 

 colour there is also a distinct eyebrow ; sides of face and under sur- 

 face of body deep ochre ; the upper margin of ear-coverts dark brown, 

 and the sides of neck streaked with the same colour ; the breast 

 sparingly spotted with dark brown, the spots diminishing in num- 

 ber towards the abdomen, and changing to bars on the thighs and 

 under tail-coverts ; under wing-coverts deep ochre, with blackish 

 spots ; upper wing-coverts a little browner than the back and much 

 mottled, with rufous margins to the greater series ; primaries black, 

 secondaries browner, barred with black, showing more plainly on 

 the inner web, which is ochraceous in the primaries, rufous ia the 

 secondaries ; upper tail-coverts ochraceous white, the middle ones 

 blackish at base and along shaft ; tail ashy brown, tipped with 

 whity brown, crossed with eight or nine bars of darker brown, the 

 subterminal one being the broadest. 



Ohs. The bars on the tail dissolve into irregular mottlings, and are 

 never quite conterminous on each side of the shaft. At the same 

 time as the bird's plumage begins to get black by the gradual ex- 

 tension of the dark centres to the feathers, a new tail is assumed by 

 a moult, the apical half of which is black, the basal half ashy brown, 

 with numerous black mottlings (as in the preceding tail), but with 

 the white of the adult plumage already appearing in a greater or less 

 degree ; the base of the tail is black at first, but this gradually dis- 

 appears with age. 



Adult male. Entirely black ; upper tail-coverts for the most part 

 white, especially the external ones ; tail white at base (generally 

 with remains of black) and at tip, with a broad black band across 

 the lower half. Total length 22-5 inches, culmen 2-25, wing 15-3, 

 tail 9, tarsus 4*45. 



Adult female. A little larger than the male. Total length 25 

 inches, wing 15*9, tail 10, tarsus 4-8. 



Hah. Brazil, through Amazonia and Guiana, into Central America 

 to Costa Hica.
