I’ve seen similar behavior from Saffron Finches, for the duration of our entire lunch, one day we watched one pound the side mirror of a 4x4 parked nearby.
I use em and they work against any birds that try perching, which the author said they were doing.
Would ultrasonic bird repeller be an option? Not sure how problematic they are for wildlife in general. I know small children can hear them and be bothered by them, but might be the least amount of work.
This is an income property, I don’t think that’s going to “fly” here :]
Maybe even less practical, but if it’s a big problem not just limited to the one house, maybe several owners can get together and hire a solution that might actually fly, something like: falconry for bird control? Sorry, wrong country…
My local bird store experts included a nice article about the ways and results one homeowner tried to reduce bird injuries.
Los Gatos Birdwatcher Newsletter; Ways to keep birds safe from window strikes
Hi, I’m looking to install some bird strike film and I live in Albuquerque. Which type (dots/horizontal or vertical lines) did you get? Did you have someone install it for you? Thanks.

Hi! Try using external screens, non-reflective films or hanging strings/ribbons to break up reflections these work better than decals alone.
We have gone with primitive - masking tape - a cross and 2 bars. Will get an aesthetic solution one day. But the birds don’t smash the window when the sparrowhawk swoops in.
On windows that were particularly prone to strikes, I took a thin artist’s paintbrush and with white latex paint, painted vertical stripes on the outside of the glass 3 inches apart. I haven’t had a single bird fly into them in the two years since. And surprisingly, the stripes don’t bother me at all - they sort of add character to the house :)
This is more for accidental strikes though. Not sure how much it would help when the issue is birds battling their reflections.
