Do you - or any of your readers – know of any effective means of
scaring off eagles (or other birds) from a hang glider? (As you’re probably
aware, in Australia we often suffer from attacks and sail damage by aggressive
and territorial wedge-tailed eagles). I’ve heard a few theories as to what to
do: imitate their screech back at them or screech first, etc. I’ve tried these,
but can’t say if it really worked. Has anyone had any success with any
particular method or device?
