woodpecker holes
Bark drilling evidence
Woodpecker holes are the cavities that woodpeckers drill into trees—small round openings for feeding on insects, or larger excavations for nesting.
The holes often appear in vertical lines on dead or dying wood.
Other birds and small animals frequently take over abandoned woodpecker holes as shelter: The bluebirds nested in an old woodpecker hole.
