Large Hummingbird Static Window Clings Anti Collision Window Decals for Bird Strikes, Glass Awareness Stickers, Stop Birds Flying into Windows, Set of 20

Almost all of the reviews that gave negative feedback clearly didn't read the instructions. THERE IS A CLEAR BACK THAT HAS TO BE REMOVED BEFORE APPLYING TO WINDOW!!! They're beautiful birds and remained on my window well enough.

Our home has very large windows. We were averaging one bird hit a day. My husband put these on the windows and we’ve stopped them from hitting the windows. I highly recommend them! Yes, you can see them but it’s a small price to pay to stop killing birds.

It took a little doing to get the thin backing off of the decals. The double scotch tape trick that they recommend didn't seem to work for me, but a sharp, pointed knife did the trick. I cleaned the windows and sprayed distilled water on them prior to applying the decals. They went on nicely and seemed to adhere well. I'll have to update this review in a month or two to determine how they're holding up and repelling the birds. They do seem thicker than the old decals that I removed.

Very pretty when the sun hits them. So far they are doing the job, I’ve had no birds crashing into the window s. Have patience as some of the backings are not as easy to get started to remove. Easy to adhere and remove to reposition.

Fell of the window 1 day after applied...material seems quite stiff in view of the thickness....will try again with another of the selections...maybe the larger ones stick better.After peeling off the backing film ( reading for comprehension helps ...) they seem to work better...

I was hoping to keep the bluebird from pecking at her image in the sliding door. It was hard to get the backing off the decals but their suggestion of using the two pieces of scotch tape did work well. The decals actually look pretty on the glass door, reflecting the light. BUT they didn't discourage the bird at all...and so not worth the cost.

I honestly didn't buy this for birds as u do not have that issue. However, I did purchase for the look and boy was I impressed. Looks so pretty in the day and oddly enough very pretty at night as it reflects the smallest light. Very easy to use and renove. No issues with them falling off.

I love these! They were easy to apply and stick really well. The best part is that they don’t hide or detract from the view outside!
