Birds also have a biological micro-barometer, that they normally use to judge their altitude, and it's also a very good weather predictor. The barometric change cycle caused by an approaching storm is easily picked up by them.

You may have noticed that when the pressure drops ahead of a storm, swallows, purple martins, etc. fly at lower altitudes.

Thanks for the added information.

Interesting, isn't it?

I have a soft spot for the eagle. Instead of getting as far away from a storm as possible or hiding they stay and soar ABOVE the storm.

Need I add that I love animals. They fascinate me.
