Habitat

Mature or old-growth boreal and montane coniferous forests with an abundance of insect-infested snags or dying trees (Winkler et al. 1995, Goggans et al. 1988, Virkkala et al. 1994, Murphy and Lehnhausen 1998, Imbeau et al. 1999). Optimal habitat includes areas with 42-52 snags per 100 acres, with snags occurring in clumps, measuring 12-16 inches dbh and 20-40 feet tall, and mostly with bark still present (Spahr et al. 1991). Cavity nests placed in dead (occasionally live) tree (commonly conifer or aspen). Sometimes nests in utility poles.
