the ground. On approaching these places, the kee-oo became

Winter Hawk. — This large American Buzzard is not un- 

 common in this vicinity, as well as in the neighborhood of 

 Philadelphia, where Wilson met with it along the marshes and 

 meadows, feeding almost wholly upon frogs. It is abundant 

 toward winter. It appears to have very much the manners 

 of the European Buzzard, remaining inactive for hours to- 

 gether on the edges of wet meadows, perched upon the larger 

 limbs of trees, and at times keeping up a regular quailing and 

 rather hoarse keigh-00, keigh-00, which at intervals is answered 

 by the mate. When approached, it commonly steals off to 

 some other tree at no great distance from the first ; but if 

 the pursuit be continued, it flies out and hovers at a consider- 

 able height. It is also an inhabitant of Hudson's Bay and 

 Newfoundland. 



Nuttall regarded the old and young as distinct species, giving 

 to them not only distinctive names, but a different distribution. 

 Taken together, his two biographies tell about all that is yet known 

 of the habits and range of the species. It is found throughout this 

 faunal province, from the Gulf States to the southern border of the 

 fur countries, has been taken at York Factory on Hudson's Bay, 

 and is common in Manitoba. 



Note. — The Florida Red-Shouldered Hawk {Btiteo linea- 

 tus alleni) is a Southern form found in Florida, and ranging on 

 the Atlantic shore north to South Carolina and along the Gulf 

 coast to Texas. It differs from true lineatjis in having the rufous 

 tinge on the head and neck replaced by brownish gray.
