ICTERUS BULLOCKII, Bon. 
Bullock’s Oriole. 
Xanthornus bullockii, Sw. Syn. Mex. Birds, Taylor’s Phil. Mag. I, 1827, 436.

Icterus bullockii, Bon. List, 1838.—Aup. Orn. Biog. V, 1839, 9; pl. 388 and 433.—In. Birds Amer. IV, 1842, 43 ;

Psarocolius auricollis, Maxim. Reise Nordam., I, 1839, 367. (Fort Pierre, Neb.) 
Sp. Cu.—Tail very slightly graduated. Upper part of the head and neck, back, wings, two central tail feathers, line from 
base of bill through the eye to the black of the nape, and a line from the base of the bill running toa point on the throat, 
black. Under parts generally, sides of head and neck, forehead and line over the eye, rest of tail feathers, rump, and upper 
tail coverts, yellow orange. A broad band on the wings, involving the greater and middle coverts, and the outer edges of the 
quills, white. Young male with the black replaced by greenish yellow, that on the throat persistent ; female without this. 
Length, about 7.50 inches ; wing, 3.80. 
Hab.—High Central Plains to the Pacific ; rare on upper Missouri ; south into Mexico. 
The subterminal portion of all the feathers in the black of the head above and back, (except 
on the posterior portion of the latter) is yellow. The black on the throat is as wide as the base 
of the bill, and extends along the sides of the bill to the black in the loral region. The rump 
is olivaceous yellow, the tail feathers brighter yellow. All the tail feathers are yellow at the 
base ; the exposed portions of the two inner are black ; the rest with a blackish tip, diminishing 
from the fourth to first. The shafts of all are black above towards the base. The under surface 
of the wings is orange yellow. 
In the female and young male the upper surface is olivaceous yellow, browner on the middle 
of the back. The black band through the eye is faintly indicated. Nearly mature males have 
a much broader orange frontal band ; the top-of head is much spotted with the same. 
The bill and tail are shaped very much asin J. baltimore. It is a larger species, and is 
readily distinguished by the yellow of the front and sides of the head and neck, with a black 
line through the eye, instead of having the whole head and neck black; lesser wing coverts 
black, not yellow; a much broader white band on the wing, &e,
