I'd like to know too. To be fair, I expect anecdotal evidence is all
you can hope for as it would be a pretty odd science experiment to
test out how to blind birds with light...

As this is a regular thread, I'll just toss in my usual comment (one
that does have some "anecdotal scientific" evidence going for it): it
is easier to *spot* animals with a bright light but it is then harder
to *observe* them. I've tried out torches and low-end night vision
gear and the difference is pretty dramatic. With the IR-boosted night
vision, mammals just don't seem worried. With a torch, they turn away
and leave a lot quicker.
