What action is recommended when approaching a nest box slowly to allow parent birds to recognize the sound as non-threatening?

Answer

Tapping the pole lightly before touching the box.

To ensure parents recognize an approach as safe, observers are advised to make their actions predictable, such as tapping the pole lightly before touching the box so the sound registers as the caretaker's familiar sound rather than a predator's approach.
