HAWKS, EAGLES, AND KITES 595 
is one of the most daring of all the Hawks, and while in pursuit of 
its prey is apparently less concerned by the presence of man than any 
other. It will dart down unexpectedly at the very feet of the farmer 
and carry off a fowl.” 
“Of 28 stomachs examined, 9 contained poultry or game birds; 2. 
other birds; 10, mammals; 3, insects; 1, centiped; and 8 were empty” 
(Fisher). 
835. Parabuteo unicinctus harrisi (Aud.). Harris’s Hawk. Larger 
upper tail-coverts, and base of tail white; lesser and under wing-coverts 
rufous. Ads.—Above and below fuscous-brown more or less washed with 
rufous, especially on the rump; tail black, its base and tip white; thighs 
rufous, under tail-coverts white. Im.—Similar, but tail without white tip 
and, seen from below, with broken bars; underparts streaked or barred 
with white; thighs barred with white. 9L., 22°00; W., 14°50; T., 10°00. a

Range.—Lower Sonoran zone in se. Calif., s. Ariz., s. N. M.,s. Tex., La., 
and Miss., s. to Cape San Lucas and Panama; accidental in Iowa and Ills. 
Nest, of sticks, etc., often in ‘chaparral’ growth or small trees. Eggs, 
2-4, white, sometimes with small cinnamon spots, 2°08 x 1°70. Date, Corpus 
Christi, Tex., Mch. 19. 
I found this Hawk a common inhabitant of the chaparral about 
Corpus Christi, Texas, where it nested in the low mesquites and hui- 
saches. Dresser observed it feeding on carrion with Caracaras and 
Vultures, but specimens dissected by Sennett contained mice, lizards, 
birds, and spermophiles. The white upper tail-coverts, as in the Marsh 
Hawk, make a good field mark, but Harris’s Hawk lacks the light, 
graceful, bounding flight of that species. 
337. Buteo borealis borealis (Gmel.). Rep-raitep Hawk. Ads.— 
Upperparts dark grayish brown or fuscous-brown, more or less edged with 
rufous, ochraceous-buff, and whitish; four outer primaries ‘‘notched,” the 
outer one not regularly barred ; wing-coverts not edged with rufous; tail 
rich rufous, with a narrow black band near its end and a white tip; upper 
breast heavily streaked with grayish brown and ochraceous-buff, lower 
breast lightly streaked and sometimes without streaks; upper belly streaked, 
spotted, or barred with black or blackish, forming a kind of broken band 
across the belly; lower belly generally white without streaks. Im.—Similar, 
but the tail of about the same color as the back, crossed by numerous more 
or less distinct blackish bands; no rufous in the markings of the underparts.

The Red-tailed Hawk resembles its near relative, the Red-shoul- 
dered Hawk, in the selection of its haunts, and, to a large extent, in
