Vermont · UplandGray (Hungarian) partridge

No current wild population is confirmed, though this species has a richer documented history in Vermont than the state's other non-established upland birds. The Atlas of Breeding Birds of Vermont's dedicated Gray Partridge account (1976-81 survey) shows a small population once real enough to be confirmed breeding, but always marginal: introduced before 1893, disappeared after the severe winter of 1904-5, then successfully recolonized (likely via spread from a large 1930 New York introduction plus local sportsman releases) and restricted in its distribution to the northern portion of the Champlain Valley, with most sightings coming from Grand Isle and the vicinity of Missisquoi National Wildlife Refuge. Even at that historical high point the species occupied only 2 of the state's priority survey blocks (1%). The Atlas explains the lack of an open season directly: the existing population was believed too small to support an annual harvest. Critically, VFWD's own current upland-game-birds page does not mention gray partridge at all, and the species is absent even from that current page, appearing only in VT's statutory game-bird list with no open season listed. No post-2010 Vermont sighting confirms a persisting population. Given the population was already down to 1% of surveyed blocks over 40 years ago and receives zero mention in VFWD's current material, the historical Grand Isle/Missisquoi pocket is not an active region today.
