1977. Cavity-nesting birds of North American forests. U.S. Dep.
Agric., Agric. Handb. 511, 112 p.
Habitat, cavity requirements, and foods are described for 85 species of
birds that nest in cavities in dead or decadent trees. Intensive removal
of such trees would disastrously affect breeding habitat for many of
these birds that help control destructive forest insects. Birds are
illustrated in color; distributions are mapped.
