Will humans be able to detect this if I use it on glass windows backed by bright (or dim) sunlight? (Hoping to deter birds).

Humans should be able to see the marker. Although the ink is virtually transparent, the marking will still be slightly visible in the form of a residue.

Can this ink be used on nonporous surfaces?

I believe so. It should dry just like any other marker and stay visible
