Northern Prairie Wildlife Research Center
The Baileys were biologists for the U.S. Bureau of Biological Survey. Vernon, a mammalogist, and Florence (C. Hart Merriam's sister), an ornithologist, traveled extensively throughout the western United States conducting general wildlife surveys. Their publications relating to Montana are included here because they contain observations dating back to the late 1800s.
