The Birds of Wyoming. 41 



range well across the state and nearly to the Montana boundary 

 on the north. Hayden took the first bird of this species from 

 Pole creek, August, 1856, which would signify that it was a 

 summer resident. Drexel took one of these birds at Fort Bridg- 

 er in 1858. In the spring of 1893 R. A. Wallen of Red Bank, 

 Wyo., killed one of these birds and had it mounted. In the 

 spring of 1894 F. J. Niswander killed a young bird near Lara- 

 mie. In early August, 1899, W. H. Wyman of Cokeville sent 

 to the University a beautiful specimen. I was away from home 

 at the time and the bird spoiled before my return. Mr. Wy- 

 man wrote me later that he had killed three or four of these 

 birds during the last ten years. The records are sufficient to 

 prove that this bird is not a straggler. 



HERONS, EGRETS, BITTERN^, ETC. 



190. Botaurus lentiginosus (Montag.). 

 American Bittern, 

 Summer resident; common. Usually breeds along the 

 swampy irrigated valleys. Jesurun, quite common at Douglas ; 

 Coues notes one specimen from Sweetwater river; McCarthy 

 from the North Platte river; Williston reports it from Lake 

 Como. The University records are from Green river, North 

 Platte river, Big Horn Basin and Laramie Plains. 



197. Ardea candidissima Gmel. 

 Snowy Heron. 



Accidental. About the first of May, 1902, Mr. Lindsey 

 of Red Mountain killed a bird of this species on Sportsman's 

 lake, about 13 miles southwest of Laramie. This specimen was 

 presented to J. A. Johnson, who had it mounted and placed 

 in his collection. The bird is a remarkable specimen in full 

 plumage. This is the only Wyoming record and probably is 

 the northernmost point in the Rocky Mountains that this spe- 

 cies has been found.
