Our study examined the specific characteristics of 58 trees with excavated cavities used by birds in Rhode Island. Forty-five percent of cavity trees used by cavity-nesting birds were red maple and American elm. Forty-one percent of cavity trees had ≥ 2 cavities. Most cavities were ≤ 0.9 m from a decay entry point such as a broken top or branch. The characteristics of trees most often used by cavity-nesting birds included: dead; broken tops; > 80% of bark cover; and low resistance to heartwood decay and ice damage. Trees with these characteristics pose little competition to crop trees and should be left standing. North. J. Appl. For. 13(1):16-18.
