Occasionally wanders southward in winter. Unlike the Black-capped Chickadee, this species spends most of its time in the interior of dense spruces, coming less readily to the tips of branches, and so it is much less easily observed. During late summer and early fall, when there is an abundance of caterpillars and seeds, Boreal Chickadees store food for winter among needles or under the bark of branches at a height that will be above the winter snow cover.
5-7 white eggs, lightly speckled with red-brown, in a cup of plant down, feathers, and moss in a natural cavity, often only a few feet from the ground.
