Weird event happening where I live

So yeah, there's been one bird that keeps flying into my bedroom window.

I have curtains on there so I'm not sure why it would constantly be doing this.

When I go outside, I can see other birds trying to do the same with my neighbor's houses.

It happens over and over again, as often as once every 10 to 15 seconds.

This is also the third straight day now, with breaks only at night.

I've never seen such a thing before and I'm curious as to what is going on here.

To be honest, it feels a little like something out of a Stephen King novel.

If this continues one more day, I'm going to take some videos and upload them since it's so weird.

Anyway, can someone explain what these birds are thinking or attempting to do?

Please and thank you.
