This species is smaller than the Red-tailed and is not as powerfully built; length 19 inches. The adults are handsomely barred beneath with reddish brown, giving the entire underparts a ruddy color. Like the last species, they rarely feed upon poultry, confining their diet chiefly to mice, rats, frogs, reptiles, etc. These Hawks nest in the larger growths of timber, usually building their nests high above the ground. The nest is of sticks, and lined with leaves, weeds and pieces of bark. They lay three or four eggs with a white ground color, variously blotched and spotted, either sparingly or heavily, with different shades of brown. Size 2.15 × 1.75. Data.--Kalamazoo, Michigan, April 25, 1898. Nest about 40 feet up in an oak tree; made of sticks and twigs and lined with bark. Four eggs. Collector, J. C. Holmes. 339a. Florida Red-shouldered Hawk. _Buteo lineatus alleni._ Range.--Florida and the Gulf coast; north to South Carolina. The nesting habits of this paler sub-species are precisely like those of the last species.

NEST AND EGGS OF RED-SHOULDERED HAWK.] Page 211 339b. RED-BELLIED HAWK. _Buteo lineatus elegans._ Range.--Pacific coast from British Columbia south to Lower California, chiefly west of the Rockies. This variety is similar to, but darker than lineatus, and the underparts are a uniform reddish brown, without barring. Their nests are like those of the Red-shouldered variety, and almost always placed high up in the largest trees. The eggs are very similar, but average lighter in markings. Size 2.15 × 1.70. Data.--Diego, Cal., April 13, 1897. Nest in a sycamore 20 feet from ground, made of sticks, leaves and feathers. 340. Zone-tailed Hawk. _Buteo abbreviatus._ Range.--Mexico and Central America, north to the Mexican border of the United States. This species, which is 19 inches long, is wholly black with the exception of the tail, which is banded. Their nests are built in heavy woods, and preferably in trees along the bank of a stream. The nest is of the usual Hawk construction and the two to four eggs are white, faintly marked with pale chestnut. Data.--Marathon, Texas. Nest of sticks, lined with weeds and rabbit fur; on a horizontal branch of a cotton-wood tree, 30 feet up.
