Chuck Nicholson's reply to our observation of the change of direction for the migrating nighthawks from east to west on Thursday night to south to northeast on Friday night makes sense. It is obvious that birds are able to detect changes in air pressure from impending weather fronts. But my question is how far away these changes have to be for birds to detect them. If they felt something from the rainstorms in Alabama, could it be possible they also felt something from the hurricane approaching the east coast of Florida? Are there any studies which would help us understand the marvelous abilities God gave to birds like these?
