IV. LIST OF THE BIRDS OF HARDING COUNTY 

 By S. S. VISHDR. 



The following list is based upon the following sources of 

 information: (i) Mr. G. B. Grinnell passed through the area 

 from northeast to southwest during July 9-16, 1874, and through 

 the western part August 17-29 with the Custer Expedition to the 

 Black Hills. His report as naturalist, published in Ludlow's 

 "Report of Reconnaissance of the Black Hills," contains some 

 statements which certainly apply to our district. (2) Mr. Sal 

 Catron of Camp Crook has lived there on the Little Missouri 

 River since 1883. Continual hunting has made him familiar with 

 the larger birds. (3) A. A. Saunders of the U. S. Forest Service 

 spent portions of November and December, 1909, and in a letter 

 has reported several interesting winter records. (4) As naturalist 

 to the South Dakota Geological and Natural History Survey, it 

 was my privilege to visit the area several times, (July 7-Sept. 4, 

 1910, June 6-20, 1911, Aug. 1-9, Aug. 3o-Sept. n, 1912), during 

 which practically every township was visited, and the most 

 interesting areas revisited.
