Hab. — Patagonia, Tierra del Fuego. Specimen in Nat. Mus. Wash- 

 ington. 



One very fine specimen, from Orange Bay, Tierra del Fuego, in the 

 collection of the Expedition, is all that we have ever seen of this bird. 

 Late authors, for the greater part, have considered it as the young of 

 the common Bateo horeaUs, of North America, with which conclusion 

 we cannot at present coincide. It may, however, be the young of 

 the western Buteo moiifamis, Nuttall, but not having within our reach 

 sufficient evidence, we must regard it as a distinct species. It is about 

 the same size as the female of the bird mentioned, and considerably 

 resembles the young of that species figured by Audubon, in Birds of 

 America, Plate CCCLXXII (Octavo edition, I, Plate VI), but is not 

 so dark colored in the plumage of the superior parts.

This fine species, well known as an inhabitant of the States of this 

 Confederacy, on the Atlantic and in the interior, is also a common bird 

 of the shores of the Pacific. It appears in fact to be diflused through- 

 out North America, from Mexico to the confines of the perpetual frost.
