The Chestnut-backed Chickadee is a cavity nester and will line their nests with the fur of deer, rabbits and coyotes. They also make a blanket of fur to cover the eggs when they leave the nest.
They store food in the fall and consume it in winter.
In the part of their range where they overlap with the Black-capped Chickadee they will nest and feed in the lower half of trees only in order to minimize competition.
A group of chickadees are collectively known as a "banditry" and a "dissimulation" of chickadees.
