Eight species of birds occur in large numbers "in appropriate habitat and season" according to the Birds of Jackson Hole Checklist, including mallards, tree swallows, cliff swallows, American robins, warbling vireos, white-crowned sparrows, dark-eyed juncos and Brewer's blackbirds.
Ninety-two species occur regularly enough "in appropriate season and habitat" to be considered common, including American white pelicans, trumpeter swans, Barrow's goldeneyes, northern goshawks, American kestrels, blue, ruffed and sage grouses, sandhill cranes, California gulls, common nighthawks, calliope hummingbirds, red-naped sapsuckers, Clark's nutcrackers, American dippers, MacGillivray's warblers, black-headed grosbeaks and rosy finches. Evidence of local breeding has been gathered in the Jackson Hole region for most of the common species.
Ninety-two species appear on a more infrequent basis, though many of them have been identified as breeders within the Jackson Hole region. Occasional sightings include Clark's grebes, white-faced ibises, harlequin ducks, golden eagles, prairie falcons, gray partridges, mountain plovers, long-billed curlews, Franklin's gulls, boreal owls, Lewis' woodpeckers, Hammond's flycatchers, sage thrashers, lazuli buntings and Bullock's orioles.
Thirty-one species that appear in the Jackson Hole region have done so unexpectedly in relation to season and range, including wood ducks, ferruginous hawks, peregrine falcons, chukars, sharp-tailed grouses, whooping cranes, pectoral sandpipers, red-necked phalaropes, burrowing owls, Say's phoebes, winter wrens, solitary vireos, Townsend's warblers, lark buntings and Harris' sparrows.
