A specimen of this bird was . shot at Salt Lake, March 21, I860. The species was first described from individuals killed in Maine, since which it has been found hi very small numbers- more abundantly 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 usuaDy seen in individuals from the Atlantic coast. The black marks on the dorsal feathers are also larger and more decided. Thg bill, too,, appears a little smaller* These differences, however, are hardly specific.

This exceedingly interesting bird was first described by Swainson , 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. MALE. General colour of back, scapulars, hind neck, belly, |
