Bird Decals for Bird Safety

Easy Print.  Print a bird, save a bird.  My brother is testing in Texas to see if it stops birds from crashing into windows. He says so far it's working - he was having a problem with it before (now if it only kept the mosquitoes away). I've been having fun with Ninjaflex decals. Use water as an adhesive on the "smooth" side. I've printed in Semiflex (shore hardness 98A) and find they drop off the window over time. The decals I printed in Ninjaflex (shore hardness 85A) are still sticking weeks later.
