Range
North America, Middle America : Southwest USA to Nicaragua
Habitat
Pine and fir forests of high mountains.
Breeds in mountain pine forests, generally at elevations of 6,000′ and above. Prefers ponderosa pine, but also occurs in other pines, firs, Douglas-firs, and in adjacent oaks. In winter, at least some individuals move down into oak woodlands in
lower foothills.

Reproduction
Details of breeding behavior have not been well studied, partly because nests are placed in the upper reaches of trees.
Nest: Placed from 30-70′ up, usually in pine, and usually 15-
20′ out from the trunk on a branch. Nest (built by female) is an open cup of moss, lichen, pine bud scales, pine needles; lined with the soft white plant fibers from the underside of silver oak leaves, and rootlets.
Eggs: Usually 3-4. Bluish white with olive and brown marks at large end. Female incubates (and male might also?), but length of incubation period and roles of the parents are poorly known.
Young: Probably both parents feed the nestlings, but details (including age at which young leave the nest) are not well known.

Feeding habits
Probably mostly insects. Details of diet are not well known. Has been observed feeding on insects, and these undoubtedly make up majority of food.
Behavior:
Usually forages in the upper third of pines and other trees. Creeps over branches and twigs of pines, gleaning insects from the twigs and from the bases of needle clusters. When not breeding, often seen foraging in mixed flocks including other warblers a
nd titmice, nuthatches, and other birds.

Conservation
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Migration
Southwestern United States to Nicaragua.
b Migration: Thought to be mostly a summer resident in our area, but at least some remain through winter. Becomes common in mountain forests by March and can still be found in numbers into October.
