Cavity Nests

Some woodpeckers, trogons, and nuthatches can excavate their own nesting holes. Other birds like chickadees, bluebirds, some owls, ducks and flycatchers use holes abandoned by their "previous owners." 

Williamson's Sapsuckers usually nest in a hole in the trunk of a partly decayed pine or aspen tree.  The nest hole can be as low as 5 feet or as high as 60 feet above the ground.
