WindowAlert Leaf Medley Anti-Collision Decal - UV-Reflective Window Decal to Protect Wild Birds from Glass Collisions - Made in The USA

These window stickers have proved effective in preventing birds flying into our windows. Be aware they have to be placed on the outside of the glass.

I didn't want anything that would catch the eye too much - I bought the leaf medley and they are attractive, don't catch the eye and the birds have stopped knocking themselves out on our big window -success!

Ok. Needed to use two at a time, placed close together.Didn't stop the crashing but birds just seemed to bump glass and fly.

Pros - arrived very quickly/can be stuck and re stuck and easily removedCons - have to warm up your window to apply and instructions say to only be applied outside window not from insideWill update how birds respond once my window feeder is up

Loved these decals, work well, easy to apply and are unobtrusive.

Soo pleased with these! I was getting quite upset over birds flying into my French windows, So far it seems to be working. I chose opaque ones which are very subtle and quite pretty!

Before we applied these we used to have birds crash into our bi-fold doors at least once a week, it was horrific! We’d come home and there would be a dead bird lying in front of the doors, or worse still we’d be sitting beside the door when the bird hit! These were really easy to apply and have been on the doors for a good few months now with no sign of peeling. We didn’t apply anywhere near as many as the instructions said were needed and they’ve still done the job. They look pretty natural, don’t obstruct your view and people have commented on how nice they look. A really good buy, don’t hesitate!

Was having a surge of bird collisions recently, with birds crashing into the windows on a daily basis (up to 7 in a single day!). Had taped some pieces of paper to the outside of the windows as a temporary mitigation, which worked but was pretty unsightly. Bought 6 packs of these about a month ago and replaced the paper on the windows with these, so far so good, no more bird collisions. Make sure you clean the window and stick these to the outside of the window to have it work best and last.Only down side is its a bit pricey - need at least 1 pack per window, so it can add up pretty quickly. But seems to be working so far, so considering it money well spent.
