Chestnut-backed chickadees build their nests on woodpecker holes or excavate their own cavities in soft rotten wood. They are also known to nest in man-made nest boxes. The nests are built using moss, lichen, fine grass, feathers, and plant fiber, and are lined using soft hair and fur. The nests are usually placed low and do not exceed 10 feet above ground.

Chestnut-backed chickadees use lots of fur and hair to make their nests. Their nests are actually 50% fur and hair. The most common hair they use comes from deer, rabbits, and coyotes. The adult chickadees also make a layer of fur about a centimeter thick which is used to cover the eggs on the nest whenever they leave the nest.
