The first intimations of the occurrence of this beautiful bird in North 

 America, were made by Mr. Drummond and Dr. Richardson, by the former 

 of whom it was found in 1826, near the sources of the Athabasca, or Elk 

 river, in the spring, and by the latter, in the same season, at Great Bear 

 Lake, in latitude 50°. Dr. Richardson states, in the Fauna Boreali-Ame- 

 ricana, that "specimens procured at the former place, and transmitted to 

 England, by the servants of the Hudson's Bay Company, were communi- 

 cated by Mr. Leadbeater to the Prince of Musignano, who had introduced 

 the species into his great work on the Birds of the United States." "In its 

 autumn migration southwards," he continues, "this bird must cross the 

 territory of the United States, if it does not actually winter within it; but I 

 have not heard of its having been hitherto seen in America to the southward 

 of the fifty -fifth parallel of latitude. The mountainous nature of the country 

 skirting the Northern Pacific Ocean being congenial to the habits of this 

 species, it is probably more generally diffused in New Caledonia and the 

 Russian American Territories, than to the eastward of the Rocky Mountain 

 chain. It appears in flocks at Great Bear Lake about the 24th of May, 

 when the spring thaw has exposed the berries of the alpine arbutus, marsh 

 vaccinium, &c, that have been frozen and covered during winter. It stays 

 only for a few days, and none of the Indians of that quarter with whom I 

 conversed had seen its nests; but I have reason to believe, that it retires in 

 the breeding season to the rugged and secluded mountain-limestone districts, 

 in the sixty-seventh and sixty-eighth parallels, where it feeds on the fruit of
