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, Icee, 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 
beyond them, during its autumnal and winter migrations. I have met with 
it in every Sta'te or Territory of the Union that I have visited. In the spring
