Bird Lite of Noirth Dakota 71 



I did not see this species in life, but found mounted specimens in Mrs. 

 Olsen's Collection at Medora, and one in the Williams Collection taken at 

 Grafton, November i, 19 12, by Henry Williams. Mr. Russell Reid writes 

 that a pair nested on the grounds of the State Penitentiary at Bismarck, in 

 1915 and 1916.

 JuDD, 1917, p. 25; not at all common, have found them breeding on the shores of 

 Lnke Alice, Ramsey County.

 24, 1920, adults and nearly grown young were found at Stump Lake. In 

 1 92 1 one was seen at Devils Lake on May 4, one near Cando on June 6,

 on May 16, 191 5.

262. Vireosylva olivacea (Linnaeus). Red-eyed Vireo.

 dent of the Turtle Mountains. 



Tliis species was at Devils Lake, May 23, 192 1, and it was quite com- 

 mon there as a summer resident. It was also common in the Turtle Moun- 

 tains in August, 1920, and doubtless occurs in all suitable habitats through- 

 out the state.
