Final Thoughts

One interesting thing about building clay bird houses with waterproof finish is that it combines creativity with real wildlife support.

Many people focus on decoration, but the size of the entrance hole and the placement actually matter more if you truly want birds to move in.

Small species like wrens or chickadees prefer holes around 1 to 1.5 inches wide. Bigger holes invite predators sometimes.
