Distribution and Status of the White-tailed Ptarmigan

Hoffman (2006) reviews (.pdf) the distribution and status of the White-tailed Ptarmigan, including these comments on introductions outside its native range:
In addition to the possibility of natural expansion, the species also has been successfully introduced into suitable habitats outside its native range, including the Sierra Nevada in California (Clarke 1989, Clarke and Johnson 1990, Frederick and Gutierrez 1992), Uinta Mountains in Utah (Braun et al. 1978), and the Pecos Wilderness Area in New Mexico (Hubbard and Eley 1985). White-tailed Ptarmigan also were released into the Wallowa Mountains in northeastern Oregon, but the translocation was unsuccessful (Evanich 1980, Braun 1993).
Hoffman’s Figure 2 (on p. 13) shows the known distribution of the White-tailed Ptarmigan, along with locations of successfully introduced populations in California, New Mexico, and Utah.
