FALCONIDiE. 



at the tip. Under parts, pale fulvous ; almost white on the 

 chin and throat ; streaked on the two latter, and blotched

Not common, but widely distributed. A specimea lived for some 

 time in my taxidermist's work-room, and would eagerly answer to his 

 name, when called, by day or night. He would come to the hand and 

 take from our fingers the bodies of the birds skinned for mounting, 

 or pounce frota his perch upon any stray mouse that ventured near 

 him. 



Fully adult birds become throughout of a deep rufous-brown, 

 blotched with dark markings. In this stage they constitute Le Vail- 

 lant's species, called Le Bougri, Ois d' Af., PI. 17. 



The note of this bird is a weak stridulous scream. It frequents 

 open country dotted with jungle, and is found also in the forest about 

 George and the Knysna.
