tree cavity
Hole in trunk
A tree cavity is a hollow or hole in a tree trunk or branch, typically formed by decay, disease, or woodpecker activity.
These spaces provide crucial habitat for wildlife—owls, squirrels, and raccoons nest in them, while bees may establish hives inside.
The old oak had a tree cavity large enough to shelter a family of raccoons.
