144 Visher, Birds of Western South Dakota. [ April 



A LIST OF THE BIRDS OF WESTERN SOUTH DAKOTA. 



BY STEPHEN SARGENT VISHER. 



The list is based upon the following sources of information: 

 (1) The birds observed while sent out by the Geological and 

 Natural History Survey of South Dakota to the Black Hills (August 

 1 to 24, 1908) and to the Bad Lands (August 24 to September 18). 

 The northern half of the Hills were thoroughly studied; and an 

 area forty miles by thirty miles, having its southwestern third in 

 the badlands, extending from the White River near Interior east 

 to Kadoka, and north to Cottonwood, on the C. N. W. R. R., 

 was gone over. Several years spent in eastern South Dakota and an 

 extensive western trip, has given the author a familiarity with these 

 birds that makes the observations, I hope, reliable. 



(2) Upon the list of the birds collected in 1857 and 1860 in what 

 is now South Dakota by H. V. Hayden (late director of the U. S. 

 Geological Survey) while on the Warren Expedition. 



(3) Upon the list of the birds collected by G. B. Grinnell, 

 Zoologist to the Custer Expedition in 1874. He entered the Hills 

 from the north July 20, continued south to the south central part 

 (Harney Peak), swung east and north, leaving at the north corner 

 (Bear Butte) August 16. 



(4) H. E. Lee, now of Pierre, has done much good work, 

 particularly upon the water birds of Bryant County, in the north- 

 eastern part of the State. 



(5) E. H. Sweet of Vermillion, South Dakota, spent from June, 

 1907, to September, 1908, on a claim just north of the Bad Lands 

 in southwestern Stanley County, and observed in the area between 

 the White River and the N. W. R. R. line, and between Interior 

 and Kadoka. He did a little collecting. Sweet was my kind host 

 during the time I spent in this area. 



(6) Henry Behrens, of Rapid City, has for several years col- 

 lected about Rapid, which lies in the eastern foot-hills. Most of 

 his collection was gathered near his ranch in Spring Creek Valley, 

 eight miles south of Rapid; all within twenty miles of Rapid City. 

 His collection consists of about three hundred and fiftv mounted
