After looking at the photography posted here I was over whelmed.
So I knew it was the right place for the question. I have an owl that visits a tree near me after dark. Is it safe (for the bird) to use a flash. I just upgraded to a 7D and have the EF-S lenses right now
The flash generally won't do any permanent harm to the bird but I would use it with restraint. Just like humans, it will lose its night vision for a period of time. Take a photo or two and then leave the bird alone to recover its vision.
