At first read I thought you meant snowbirds..
But then I remembered the spooky nature thingy where animals split when things are about to go nasty.
I, for one, am fortunate that Hurricane OLAF last February took a right turn just before my island. It was a cat 5, and life would not have been the same, being just a little difficult to evacuate anyone off island.
Several years we put a new front porch on the house.
Hubby never has time to just go sit down and watch the world go by but one day I talked him into it.
He and I and my old dog went out to watch the sunset.
Suddenly, the air became utterly still.
The bazillions of chirping insects went completely silent.
All the birds in the area streaked by us, headed east into the woods.
[all of this happened in a matter of less than a minute]
I turned to hubby and said "What the....?".
No sooner had the words come out, the worst hailstorm I've ever seen hit like a freight train.
Tennis-ball size chunks of ice flew -horizontally- onto the porch, thrown by a terrifyingly strong wind.
I jumped down and threw myself over the old dog to protect her from the merciless, pounding hail and there we huddled for at least 10 minutes until it abruptly stopped.
The sun came out, the birds began to sing and the bugs started their incessant chirping again.
A solid foot of mid-July "snow" lay upon my lawn.
Hubby said snidely "I finally came out and sat on the porch with you. Happy now?!?"....:))
[and the old dog never did go up on the porch again]...LOL!
*Always* watch the critters.
