Breeding Range Map
Metadata (Data about data or how the map was made)
This species is locally common at very high elevations in rocky Alpine/Parkland areas of the Cascades. However, it is absent from similar habitats in the Olympic Mountains. This species forages and nests among Alpine/Parkland tundra, rocks, willows, and snow fields.
Good habitat in the core areas of use included all rocky and nonforested areas in the Alpine/ Parkland zone.
Washington breeders represent the 'Rainier' subspecies, Lagopus leucurus rainierensis. White-tailed Ptarmigan are exclusively found breeding in Alpine/Parkland rocky or tundra habitats, generally between 5000 and 7500 feet. Few records exist from the many areas of suitable habitat, but this is due largely to the remote nature of this habitat. The subspecific status of the White-tailed Ptarmigan is controversial; the proposed subspecies are probably not valid, instead representing a decline in size and darkness of summer plumage. Although BBA data are lacking, it is likely that this species nests on Mount Adams. They formerly nested on Mount St. Helens, though these birds may have been blown to Alberta after the 1980 eruption! In any case, ash fallout has covered most of the formerly suitable habitat on this mountain. In Pend Oreille County, this species is apparently not found on Mount Salmo.
