HABITAT DESCRIPTION:
Rare to uncommon in the mountains, usually preferring forests of conifers above 3,000 ft. (Hamel 1992, Simpson 1992). Potter et al (1980) lists the sightings of fledglings/immatures in the piedmont and coastal plain suggesting the possibility of widespread nesting outside of the mountains.

Breeds primarily in coniferous forests (Adkisson 1996), although Ehrlich et al (1988) states crossbills will also breed in mixed forests. Kaufman (1996) lists the 'timing and distribution of nesting as quite irregular,' with breeding often occuring when 'cone crops are best.' Nest are hidden well in dense foliage on lateral branches, near or away from the trunk (Adkisson 1996). It is often constructed of conifer twigs, barks strips, grass, and rootlets, with fine grasses, lichens, needles, mosses, feathers, and hair lining the inner cup (Adkisson 1996, Kaufman 1996).

Forages on the cones of conifers including, spruce, pine, fir, and hemlock (Adkisson 1996). Foraging occurs in the canopy of conifers, primarily near the cones, where the conifer seeds are retrieved and insects are gleaned (Hamel 1992). Crossbills will also eat buds of various trees, deciduous and weed seeds, and berries (Kaufman 1996).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Coniferous and mixed coniferous-deciduous forests; also pine savanna and pine-oak habitat. In migration and winter occurs in deciduous forest, and more open scrubby areas.

Nests in conifers, 1.5-25 m above ground, toward outer end of branch (Terres 1980).
