Interesting Bob,
 
You'd certainly expect birds should be able to sense the danger through changes in pressure, visual stimuli, etc. Watching on a smaller scale you can see birds skirting the edges of even smaller cloud bursts regularly. Othertimes taking advantage of stirred up surf along a leading edge. Something like a major hurricane would certainly be good to get out of the way of, so it isn't surprising. It would be interesting to see if others noted the same in reverse on say the upper Texas Coast. That is flights peeling west to get out of the way! Big mysteries for sure and fun observationsinto bird behavior.
 
Best,
 
Jeff

Subject: [FLBIRDS] Black Tern storm behavior



Hi all,

    As Gustav approaches our end of the Gulf Coast, we are seeing a phenomenon 
that we have witnessed when previous storms have approached the northern Gulf 
Coast when the center is forecast to past west of Pensacola. For a day or two 
ahead of the storm, against stiff east winds, a steady procession of Black
Terns 
fly east along the coast, as though they sense the worst weather will pass to 
the west of them. This involves thousands of terns and may go on for a day or 
two until the weather situation worsens. There must be a biological mechanism
at 
work here. Any thoughts on this?
