Nevada.
Habitat:
Found in montane coniferous forests (primarily
pine and fir). Usually found at elevations of 1200-2800 m during nesting season,
but may descend to lower elevations during winter. In Idaho, species is restricted
to mature or old ponderosa pine and mixed coniferous forests.

Eats seeds of ponderosa
and sugar pine, spiders, beetles, ants, fly larvae, and other insects.

Constructs nesting cavity in standing
snag/hollow tree; may use same tree year after year. Forages mainly on trunks
of living conifers by prying off loose bark to obtain food. But may also obtain

in habitats ranging from dry meadows to partial cuts to forest edges.
