This species was first described by Wilson, from a male speci- 

 men which he shot in the early part of June, on the borders of a 

 marsh, within a few miles of Philadelphia, the only specimen that 

 he ever met with ; according to Mr. Audubon, it ranges from Tex- 

 as northward to Nova Scotia, and throughout the interior to the 

 Columbia River. The specimen in my possession was shot by S. 

 F. Baird, in Cumberland County, Pa. ; and a few years since, a 

 specimen was obtained by Mr. Bell on Long Island, the only one 

 which I have known to have been procured here.
