What I find fascinating about this is that there's probably a set of neurons in bird brains that specifically fire when looking at vertical lines. Here's a live recording of this effect from a cat[0], also known as the Hubel and Wiesel[1] experiment. Now those are being triggered, causing the bird to avoid the glass. This is an exceedingly simple solution to the problem. Very impressive!
