46 BIRDS OF PREY. 



HARRIS'S HAWK. 

 Parabuteo unicinctus harrisi. 



Char. Prevailing color black, sometimes chocolate brown, tinged with 

 chestnut on the rump ; shoulders and lining of wings chestnut ; tail-coverts, 

 base of tail, and terminal band, white. Length about 20 inches. 



N^est. On a cliff or in a tree, — usually the latter; a mere platform of 

 twigs and roots, lined with grass.

 and pools. Mr. Sennett, however, describes those he saw along

 mice, and gophers.

 the young the tail is grayish brown crossed by some nine dark bars, 

 and the underparts are white with brown streaks. Length igj^ to 23 

 inches. 



Nest. In a high tree ; of sticks, lined with grass, sometimes with 

 feathers. 



Eggs. 2-4 ; whitish or bluish white, usually heavily spotted or blotched 

 with reddish brown; 2 30 X 1.80. 



This beautiful Buzzard inhabits most parts of the United 

 States, being observed from Canada to Florida ; also, far 

 westward up the Missouri, and even on the coasts of the 

 northern Pacific Ocean, by Lewis and Clarke. Wilson found 

 the young to be fully grown in the month of May, about 

 latitude 31° on the banks of the Mississippi; at this period 

 they were very noisy and clamorous, keeping up an inces- 

 sant squealing. It also occasionally nests and breeds in large
