Wing, 18.25-23.70; tail, 8.70-13.00; culrnen, 1.20-1.60; tarsus, 3.25- 
4.30; middle toe, 2.40-3.30. Adult :—General color deep black, the 
lower parts posterior to the breast (including lining of the wing) pure 
white, and the lesser and middle wing-coverts ash-gray; the white and 
ashy portions narrowly and closely barred with dusky slate or black¬ 
ish; chin, throat, and cheeks paie grayish with black sliaft-streaks; 
feathers of the neck and breast, also the upper tail-coverts and the 
rectrices, sometimes minutely tipped with white or grayish. Young :— 
Above chiefly black, the wing-coverts barred with grayish and ochra- 
ceous-white (in older specimens), or irregularly mottled with black and 
ochraceous (in younger individuals). Head streaked with black and 
ockraceous-wkite, lower parts mixed black and ochraceous, the relative 
amount of the two colors, and the depth of the ochraceous tint.varying 
with the individual, but the ochraceous usually predominating poste¬ 
riorly, the former being mostly in large suffused spots, chiefly on the 
breast and sides. Tibiie usually immaculate, but sometimes narrowly 
barred with blackish. 
Mr. Sharpe describes the tail of the “young male” as “ashy gray, 
mottled with black, more distinctly toward the apex, which is entirely 
black”; but we have seen no specimens in which the tail is not.entirely 
black, even to the extreme base, except a narrow grayish terminal mar¬ 
gin, present in most specimens. A young specimen from Brazil (No. 
50,929, Sr. Hon Fred. Albuquerque) is nearly uniform black beneath 
as far back as the tibire and crissum, which are deep yellowish ochrace¬ 
ous, with irregular black bars on the former, and zigzag spots of the 
same on the latter. In this specimen, the wing-coverts are pale gray, 
nearly white anteriorly, everywhere barred with dusky, with but little 
admixture of ochraceous; the pileum and nape are also nearly uniform 
black, nearly all the white or ochraceous being beneath the surface. 
An adult from Bogota (No. 66,323) differs from Chilian examples of 
the same stage in having a glaucous or chalky cast to the black por¬ 
tions of the plumage, especially on the head, neck, back, and jugulum ; 
the slaty bars of the abdomen, etc., are also narrower and fainter, those 
of the crissum being much broader and darker than elsewhere. 
The tail and upper coverts are more often tipped with grayish than 
with white. 
In an adult specimen, the bill was “black at the tip. yellowish-green 
at the base; eye light hazel; legs and toes chrome-yellow; claws 
black. Total length, 18J inches.”—(Scl. & Salv. P. Z. S. 1869, p. 155.)
