Native name Pita Venado. Not uncommon in thinly wooded savan- 

 na regions. 



Eye golden brown ; bill black, blackish at base ; cere chrome yellow ; 

 feet chrome yellow. 



This species is thoroughly detested by the hunter who may be 

 bent on bagging venison, for his game is very frequently startled by 

 the alarm notes of this hawk, which perched on the topmost branch 

 of some tall tree is sure to note the skulking form of the hunter and 

 instantly sound an alarm understood by all the woods people.
