It occurs within moist coniferous and mixed forests with well developed canopy cover and an abundance of coarse woody debris. Nests made of bark are often located under loose bark. Breeding occurs from January to August but most young are born in March. Young disperse after leaving the nest. Individual home ranges are thought to be long and narrow, running parallel to streams.
Population density is low and tends to be higher adjacent to streams.
This species occurs within coastal forests of the Pacific Northwest, from southwest B.C. to northwest California. Coarse woody debris, dense herbaceous and shrub cover, and forest litter are critical for security cover. Selected references Galindo-Leal, C. and J.B. Runciman. Kremsater, L. and L. Andrusiak.
