Steve,
Probably the best answer, is to have someone shine the spot into you
eyes (after they have adjusted to the dark) from a distance of some
10m. If you find it uncomfortable, there is a good chance that
nocturnal birds or mammals will be similarly affected.
Cheers,

Dear fellow nature lovers,
I am posing a question around the use of high powered torches for
viewing
our nocturnal counterparts.
What are the thoughts around a super bright rechargeable torch
(similar to
the 1,000,000 candle power one I purchased just the other day...)
doing any
damage to our little friends eyes on a dark night? Not that I would have
done such a thing....
Cheers

PS. Any discovery of a pair of White-throated Nightjars and a pair of
Sooty
Owls in Bunyip State Forest, Victoria, with burned out retinas since
Tuesday
night would be purely coincidental...
