WINTER FALCON. 
Length of the Winter Hawk twenty inches, extent forty-one 
inches, or nearly three feet six inches; cere and legs yellow, 
the latter long, and feathered for an inch below the knee; bill 
bluish black, small, furnished with a tooth in the upper man- 
dible; eye bright amber, cartilage over the eye very promi- 
nent, and of a dull green; head, sides of the neck, and throat, 
dark brown, streaked with white; lesser coverts with a strong 
glow of ferruginous; secondaries pale brown, indistinctly barred 
with darker; primaries brownish orange, spotted with black, 
wholly black at the tips; tail long, slightly rounded, barred al- 
ternately with dark and pale brown, inner vanes white, exte- 
rior feathers brownish orange; wings, when closed, reach rather 
beyond the middle of the tail; tail-coverts white, marked with 
heart-shaped spots of brown; breast and belly white, with nu- 
merous long drops of brown, the shafts blackish; femoral fea- 
thers large, pale yellow ochre, marked with numerous minute 
streaks of pale brown; claws black. The legs of this bird are 
represented by different authors as slender; but I saw no appear- 
ance of this in those I examined. 
The female is considerably darker above, and about two 
inches longer.
