CollidEscape 3/4" x 40' Clear Bird Tape - Window Decals to Prevent Bird Strikes - Bird Strike Prevention for Windows - Cover Two to Three Windows

Easy to use. Looks good. Could have used a 46' roll to cover a patio door every two inches . Ordered another roll to finish last row on door.

The clear version of this tape is very easy to apply to windows or doors and is fairly unobtrusive to the human eye once installed. I have two doors on opposite sides of a room that birds were flying into because it looked to them like they could just fly through the house from outside. This is a nice looking solution and saves bird lives, perfect!

It's worth pointing out a few things - first, this needs to go on the outside of the window, bear that in mind. Second, it's not invisible, not even close. Third, you don't need to buy loads of this and space it a few inches apart like it recommends, we've put our lines about a foot apart and it has completely eliminated birds flying into the window. The tape has held up, even with regular window washjng, with no sign of peeling, even after a year

After birds began to hit my front windows, one of whom was severely injured, I went on a hunt for a product to help prevent collisions. I read reviews for dozens of similar products and finally just took a chance on this one. I followed the spacing instructions to a tee, and this honestly did work! Not the most attractive, but if you do it carefully, the stickers kind of look like blinds from the road. I put them on the top half of my windows, as the bottom halves are screened and the birds weren’t as drawn to the lower halves.Most importantly, the birds are safer and I haven’t seen one bird injury since!Also worth noting, for fellow humans concerned about their bird friends: a few weeks after putting up these stickers, I also moved my bird feeder to a more strategic location (read online - I think the rule is within 3 feet from the nearest window//too close to swoop in super fast), or more than 10ft so they don’t notice it) and that no doubt also helped!

I've been trying to come up with a solution for bird collisions but this isn't it. I'm sure it's effective I just don't like the aesthetic. Even measuring and being careful it's impossible to get these perfectly straight so if it's a room you use a lot you'll see it every time you look out. It also gives the impression of bars on the window more than I'd hoped it would which changes the ambiance of the room. If it's for shed windows or somewhere you don't spend a lot of time then it's probably fine but I can't stand how it looks.
