Nest description: of soft materials, with base of rotten wood chips or lichen, moss or grass, topped with loose fur or hair from mammal scat, owl pellets or other sources, (feathers?). Distinct cup molded in fur, then plugged with a blanket of looser fur used to cover eggs when not being incubated.

Eggs are ovate, smooth shell with little or no gloss, pure dead white to entirely marked with reddish brown dots which may be concentrated on the larger end. Less heavily marked than Black-capped Chickadee eggs.

The student of Nature wonders the more and is astonished the less, the more conversant he becomes with her operations; but of all the perennial miracles she offers to his inspection, perhaps the most worthy of admiration is the development of a plant or of an animal from its embryo.
