STANLEY’S HAWK. 
( Falco Stanleii, nobis. Astur Stanleii, Audubon, pi. 36.) 
Spec. Charact. — Above dusky brown, a little varied with white ; 
beneath cinereous with oblong dusky spots. Tail long and 
rounded, extending much beyond the wings, with 5 broadish 
dusky bars ; cere and legs pale yellow. 
With this fine new species of Audubon we are yet 
unacquainted. It appears, however, nearly allied to 
F. Cooper ii, with which it ought to be compared. It is 
spiritedly represented, with its mate, in the act of pursu- 
ing and nearly overtaking a Bluebird. 
About 18 J inches long. Wings barred. 1st primary very short 
as well as the 2d. The 5th longest. — Male } with the head marked 
with dusky white and rufous on each feather. Female , with the 
head dusky. Beneath cinereous, with oblong dusky brown spots ; 
femorals rufous- white, with oblong, pointed spots. 
Subgenus. — Ictinia. ( Viellot . Bonap.) 
Bill short, narrowed above ; the upper mandible angularly lobed ; 
the lower distinctly notched; cere glabrous; nostrils rounded. 
Tarsi short, slender, scutellated (or covered in front with a row of 
broad scales) feathered for a short space ; the outer toe connected at 
base by a membrane. The nails short and not very acute. — Wings 
very long, extending to the end of the tail. 3d primary longest. 
Tail nearly even. 
Bold species; feeding on small birds, reptiles, &c., but chiefly 
on insects. They fly out in easy sailing circles at a considerable 
elevation. — Note. The birds of this section appear to be intermedi- 
ate between the Falcons and true Kites, and in manners they are 
somewhat related to the Buzzards.
