Colorado · Whitetail rut
Whitetail rut dates in Colorado.
Colorado's whitetail rut peaks November 10–20 in the eastern plains river bottoms — the only part of the state where huntable whitetail populations exist.
Whitetail in Colorado are concentrated along the eastern plains river systems (South Platte, Arkansas, Republican drainages). The rest of the state is mule deer country with a separate, earlier rut window. Whitetail peak conception clusters in the second half of November in the river-bottom habitat. Colorado Parks and Wildlife publishes deer-program data covering both species.
