Montana · UplandGray (Hungarian) partridge

Gray partridge was introduced to Montana in the early 1900s and has since spread across the state's cultivated prairie region, but independent sourcing (agricultural-extension and birding references) converges on the north-central and northeastern grain-belt counties, namely Montana's "Golden Triangle" (the Shelby / Great Falls / Havre wheat-farming triangle) and the broader Hi-Line, as the strongest concentration, since the species depends on a mix of grainfields, winter wheat stubble, and weedy/brushy field margins that this region supplies at scale. FWP's own regional game-bird materials corroborate this at the survey-region level, naming the North-Central region (Rocky Mountain Front/Hi-Line and the Great Falls-to-Lewistown corridor) and Northeast Montana (the Havre area and the region's western half) as strong partridge country, while also listing gray partridge as present in the Southwest region's Townsend area alongside pheasant, mountain grouse, and turkey, a real but secondary population outside the core grain belt.
