Another option is Feather Friendly (disclaimer, I have no ties to the company), which makes UV-reflective dots, about .25” square, that come in long tape strips that you apply either vertically or horizontally to a window, rub them firmly so the dots adhere, then lift away the clear tape. The only glass in our house that didn’t have external screens was our rear slider, where we had window strikes. I applied Feather Friendly in a grid three (I believe) years ago and have not had a single strike since then.
A second option is Collide Escape, which Hawk Mountain has used with great success on its large windows at the Acopian Center and the Education Building. It’s an external, UV-reflective film that can be custom-made with art or designs visible from the outside to people, while from inside the window looks much as it would if it had a normal screen. Same disclaimer applies. This approach is pricier.
And finally there are Acopian Bird Savers, which are simply long cords hanging vertically in front of a window, moving in the wind and providing a visual barrier to a flying bird. They are available for purchase at https://www.birdsavers.com but the site also provides DIY instructions for making your own out of parachute cord.

We've experimented with a couple different brands bought through Amazon and the less expensive one has been just as effective as the pricier one. We chose the leaf-shaped ones to blend in with our wooded property and even though they're only semi-translucent, they don't detract from the view at all. And the only time any of them ever peeled off was when we needed to power-wash the sunroom siding.

You'll know when that's necessary because you'll start to experience bird strikes again. And secondly, the decals aren't very large so you'll likely need to buy more than one set to have enough for full coverage.
