STANLEY HAWK. 189 



large for the size of the bird, of a duUish- white colour, strongly granulat- 

 ed, and consequently rough to the touch. It was on discovering one of 

 these nests that I wounded the second adult male which I have seen, but 

 which never returned to its nest, on which I afterwards shot the female re- 

 presented in the Plate, in the act of pouncing. I have several times found 

 other nests of birds of this species, but the owners were not in full plumage, 

 and their eyes had not obtained the rich orange colouring of the adult birds. 

 Those wliich I have observed near the Falls of Niagara were generally 

 engaged in pursuing Red-winged Starlings, over the marshes of the neigh- 

 bovirhood. When tliis Hawk is angry, it raises the feathers of the upper 

 part of the head, so as to make them appear partially tufted. The cry 

 at this time may be represented by the syllable hee, kee, kee, repeated 

 eight or ten times in rapid succession, and much resembling that of the 

 Pigeon Hawk [Falco columbarius) or the European Kestril. The young 

 of this species bear no resemblance to those of the Goshawk, of which a 

 figure will be given in the same Plate with the adult of the Stanley Hawk.
