Nest Box Plans
Mount nest box on a tree trunk or hang from a limb from chest level to just out
of reach, higher only if necessary.
Chickadees commonly nest in natural or abandon cavities, or excavate their own
cavities. Place a few chips on the nest box floor. Remove the nest after the brood
rearing season is over.
Mountain Chickadees are year around residents and might take
advantage of northern winter warming roosts.
