Is There a Difference Between Bird Decals on the Inside and the Outside of the Window?

If you can correlate multiple witnesses saying it's the same person, that's hugely important. This is really helpful if you want to maximize the utility of each witness. New research finds that placing bird decals on the inside surface of windows does not reduce bird strikes. It is outside. If you put them on the outside, they work really well. They reduce bird strikes and bird deaths.
