It would seem best for the real bad wind to come during the daytime...when the birds are on the ground. They can hunker down and ride it out like all the other critters.
However, with this storm the bad winds came at night. Who knows what a turkey does roosting and the winds start gusting at 60+. Maybe they get down to lower branches and hang on tight. Or maybe they get on the ground if it gets bad enough? My guess is their instinct is too strong to get on the ground at night...they would probably rather die.
Overall, these birds are tough.. and the winds in Central Fla (Osceola parts) didn't get too out of control.. The Keys, Naples, Fort Myers got the worst when it comes to wind speeds
