Many birds make knocking sounds as a way to communicate or find food. This behavior is common among certain species. It helps them mark territory or attract mates.

You can tell if the bird is talking or working.
Nuthatches
Nuthatches also knock, but their sounds are softer than woodpeckers. They tap on branches or trunks to find insects. They sometimes use knocking to communicate with mates or young ones.
| Nuthatch Species | Knocking Purpose | Sound Type |
|---|---|---|
| White-breasted Nuthatch | Communication and alert | Soft tapping |
| Red-breasted Nuthatch | Territory marking | Quick knocking |
| Brown-headed Nuthatch | Finding food | Light taps |
