of birds and bats
Airfoilmod,
Not a stupid question at all, it may well be that wx attracts birds, hence the need for open minds and thorough investigation. Let us not forget that the tips and tricks from old timers have usually evolved for a very good reason and to dismiss them out of hand may very well be foolhardy , at least until we have definitive scientific evidence.
PS. if you wish to avoid bats, dont fly in caves or under trees.
