Window Decals for Birds Strikes, DELLAN 35 Anti-Collision Bird Deflectors, Suncatcher Stickers Rainbow Window Clings for Glass Windows

These spheres are pretty, easy to apply, and are effective preventing the birds from crashing into the windows.

My 20 year old loves these for her bedroom window. They stick on window without leaving a trace when you remove. These adhere well but you can apply and move and they stick again. They have a prism effect when they are on window and sun shines in and reflect rainbow colors onto the wall. My biggest fear is what they would look like on the front of the house but you can’t tell they are there from far away outside when people pass by. Good fun purchase and stocking stuffer Perfect for dorm rooms too!

I have had a blue bird trying to give himself a severe concussion on my back patio door for weeks! I had originally taped paper to the top half of my patio door glass to deter him (it obviously worked, but sure my neighbors thought I'd finally lost my mind...). I came across these and thought that for the price, I would try them out.They actually work at detering the blue bird from knocking himself out! I was pretty pleased because he was very determined. The only gripe I have is that when it gets humid or water gets behind them, they fall off. But they are easily removed (like decorative vinyl window clings) without any residue or damage to your glass .

I have a bird run into our large sunroom windows almost everyday. I bought the snowflakes and also another style. They have been up nearly a week and no bird strikes. I put about 4 decals (snowflakes and some large 5” circles) on each glass. When I first applied the decals, I used only a very damp sponge to apply the water and they did not adhere very well. I then used a spray bottle and they clung to the windows immediately. The trick is to use a lot of water. I applied them when the temperature was upper 40’s and again, no trouble with adhesion. I would definitely buy these again!

They are cute and great for the price. Easy to put on. What I didn’t like is they are clear. I was expecting white. I painted them white so I could put them in a clear window.

I got these because I constantly have birds divebombing into my windows that are right behind the feeder, and I was worried about them getting hurt or worse.There were more than enough for my bird feeder adjacent windows but I liked them so much I put them on every other window facing the sun, because they cast a lovely rainbow over the house that's fun and makes me very happy.As for bird-avoidability, I haven't had any crashes since I put them up.

After putting three of these on my office window, I continue to have bird strikes from multiple species.

I live in Minnesota and needed to apply these when it was warm but didn’t order them on time. It was warm enough yesterday so I was able to apply them. It was a little tedious, trying to get all the air bubbles out as it’s got a bunch of little lines in it and so it’s kind of hard you can see in my pictures I didn’t do very well with that so I’ll see How well they stay up when it gets in subzero temperatures. They don’t look bad on the windows from the outside of the inside so far. I did not put them on my whole window, but around the edges. Had a lot of birds out today didn’t have any crashes yet, so I will report if my birds flying into windows comes to a minimum or stops. As you can see in the pictures My Window is very reflective to the outside.Update:It has been colder now and all the decals have fallen off the window.
