Greetings. Over the years I have often though that, when the air pressure falls -- a storm is on the way -- the bush birds go quiet. Less calling, less movement.

What are your observations, thoughts and knowledge about this?
- Have you observed that they go quiet when the glass is falling?
- If so, do you have a hypothesis as to why this occurs?
- Do you know of any scientific literature on the topic?
- Or am I on a completely wrong track?

Thanks - David
