PaRABUTEO UNICINCTUS HARRISI.

chestnut on the rump ; shoulders and lining of wings chestnut ; tail-coverts, 
base of tail, and terminal band, white. Length about 20 inches.

and the underparts are white with brown streaks. Length 193^ to 23 
inches.

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

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
