HAWKS, EAGLES, AND KITES 295 



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). 



335. Parabuteo unicinctus harrisi (And.). 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. ?L., 22'00; W., 14'50; T., 10*00. & 

 L., 19-00; W., 13-25; T., 9'50. 



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). RED-TAILED 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. 

 cfL., 20-00; W., 15-50; T., 9'25; B. from N., '95. 9 L., 23'00; W., 16'50; T.,

 and irregularly marked with shades of cinnamon-brown, 2'40 x 1'85. Date,

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
