A specimen of this bird was shot at Salt Lake, March 21, 1850. 

 The species was first described from individuals killed in Maine, 

 since which it has been found in very small number — more abun- 

 dantly about Carlisle, Pa., than anywhere else. The Salt Lake 

 specimen agrees with one brought from the upper Missouri by Mr. 

 Audubon, in having a more grayish tinge than that usually seen 

 in individuals from the Atlantic coast. The black marks on the 

 dorsal feathers are also larger and more decided. The bill, too, 

 appears a little smaller. These differences, however, are hardly 

 specific. 



Length of Salt Lake specimen 5f inches.

This exceedingly interesting bird was first described by Swain- 

 son and Richardson, from a specimen procured by the latter. 

 May, 1827, on the Saskatchewan River, in lat. 54°. But a single 

 individual was obtained, which was subsequently presented to the 

 Museum of the Zoological Society of London. From this, all the 

 published descriptions have been made, even that by Mr. Audubon, 

 who was unable himself to procure a specimen. For the sake, 

 therefore, of multiplying comparisons, we shall present an original 

 description taken from the bird brought home by Captain Stans- 

 bury. This was procured on the 21st of March, 1850, in Salt 

 Lake City.
