We went out today to soap the windows of the killer corridor. Lynn read that this method can be effective, and it's certainly a quick fix. So, with stepladder, a bar of soap, and fifteen minutes, we tried to create a visual barrier for our resident flocks.

Birds please fly over!
With the added grids of soap it seems visually much more confusing, hopefully this will deter attempts to fly through the glass.
Apologies to the feathered denizens of West Campus, we are trying...
