At dawn, the bird singing in the trees dances. Does that mean it won't rain today

Every morning at dawn, the happy birds begin to sing, which means that it basically doesn't rain today. This is more than ten years' experience. Whenever it rains, I can't work, and sometimes the weather forecast is not very accurate, so I refer to the forecast of natural animals.

When I was a child, a text called "Seeing the Weather from Clouds" was simply amazing.
