 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 tall, and terminal band, white. Length about 20 inches.

 and the underparts are white with brown streaks. Length 19^ to 23

 feathers.

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

 latitude 3 1° on the banks of the Mississippi ; at this period
