In Alaska, occurs in the boreal forests zone. Primarily breeds in mature and diverse stands of spruce, fir, larch, and cedar (Tyler 1948, Simpson 1976, Adams and Morrison 1993, Harrap and Quinn 1996, Campbell et al. 1997). Excavates own nest in tree snags and rarely uses existing cavities or nest boxes (Ghalambor and Martin 1999). In the Yukon, seldom observed outside of spruce-dominated or mixed forest, and is primarily at lower elevations. Frequents bird feeders in the winter (Alexander et al. 2003).
