This state's classification carries no date range for the species.
Small naturalized/introduced populations exist in some western Montana valleys, but the species is not included in Montana's statutory upland-game-bird definition (MCA 87-2-101) and carries no season, bag limit, or license requirement in the 2026 regulations.
Confirmed absence: the species is present in Montana but has no regulated season (not_regulated classification), consistent with no survey infrastructure — Montana FWP runs no California quail program.
