100 SHARP-SHINNED OR SLATE-COLOURED HAWK. 



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

 bourhood. When this 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 kee, 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.

PLATE XXV.— Male and Female. 



It is mentioned in the Fauna Boreali-Americana, that a specimen of this 

 bird was killed in the vicinity of Moose Factory, and that it has been 

 deposited by the Hudson's Bay Company in the Zoological Museum of 

 London. This specimen I have not seen, but confiding entirely in the 

 accuracy of every fact mentioned by the authors of that work, I here adduce 

 it as a proof of the extraordinary range of this species in America, which 

 from the extreme north extends to our most southern limits, perhaps far 

 be)^ond them, during its autumnal and winter migrations. I have met with
