Wildlife Gardening: What do you do to help prevent birds from hitting windows?, 1 by Stelco

This was the north side of my house before the fire. I noticed window strikes almost as soon as I moved in. Most were not fatal, but too many were. I reduced window strikes by about 95% but the solution wasn't a decorator's dream. I went to Wal-Mart and got clear suction cups with hooks on them in the craft section of the store. Then I used a box cutter to slice long, thin strips out of a black plastic garbage bag. Spread some Vaseline on the inside of the suction cups (they stay up a lot longer if you do this). Double over one end of a strip a couple of times and poke the end of a hook through the multiple layers of plastic and crimp the hook down with pliers. Get up on a ladder (if necessary) and attach to top of window. The slightest breeze makes these strips move and just by breaking up the reflection it helps. I’d hang about eight strips on this set of windows. You get used to them and they do work – cheap, too!
