dish ; the under part whitish, with oval longitudinal 

 brown spots. As they advance in age, the spots of 

 the belly and thighs become transverse blackish lines, 

 and the white increases at the throat and bottom of the 

 neck ; the plumage of the back becomes at the same 

 time more uniform, and is radiated brown, with black- 

 ish ash stripes ; the tail is brown above, with pairs 

 of reddish spots ; and underneath are pale bands, 

 which diminish in size with age. The feet and the 

 arc of the beak are sometimes blue, and sometimes 

 yellowish. 



Found also in New Holland. 



These differences may be observed, Enl. 470, the 

 young ; the Yearling Falcon, F. Herotinus, Bris. ; 

 421, the old female ; 430_, the old male. Frisch 

 gives but one young Falcon^ pi. Ixxxiii. Edwards 

 has the old female, pi. iii. ; the young, pi. iv. 



Those called in the PL Enl. Faiicom pekrins, {Falco 

 stellaris, F. peregrinus, Gmel.) seem to be young, ra- 

 ther blacker than usual. 



This is the celebrated species which has given its 

 name to falconry. It inhabits all the north of the 

 globe, and builds in the steepest rocks. Its flight is 

 so rapid, that there is scarcely any part of the world 

 it does not visit. It pounces on its prey vertically, as 

 if it fell from the clouds. The male is used against 

 magpies and other small birds, and the female against 

 pheasants, and even hares. 



The Barbary Falcon, Lath. F. Barbarus, Gmel. 

 Alb. iii. t. 2. is a variety of this.
