Cavity-Nesting Birds of North American Forests Agriculture Handbook 511

This handbook opens a window onto the lives of the 85 bird species that depend on tree cavities for breeding across North America’s forests. It details each species’ preferred habitats, the size and shape of the hollows they need, and the foods that sustain them, especially the insects they help keep in check. Colorful illustrations and clear distribution maps make it easy to recognize woodpeckers, nuthatches, swallows and owls even for listeners new to birdwatching.

Beyond identification, the text explains why old, decaying trees—often called snags—are vital to forest health. By showing how these birds curb bark‑beetle outbreaks and support biodiversity, the guide highlights the ecological cost of removing dead wood. Listeners will come away with a deeper appreciation for the delicate balance between forest management and the feathered allies that protect our woods.
