UFO appears to consciously avoid being filmed from afar?

I was working outside on a deck job when I saw a crow chasing off a large hawk that I assumed was getting too close to its nest. It had been occurring over the course of several days, I'd look up and notice these two in some sort of acrobatic aerial dance, almost playful so I decided to capture some of it on my iPhone 13 camera. One day I saw the birds were doing their thing and moving closer to where I was working so I decided to film them. As I was filming I noticed a small bright glowing object moving slowly from right to left at the bottom of my screen. At that point I began to focus on it and after a second or two it paused and reversed direction I followed it and noticed it stopped again and switched back as I was adjusting to the switch and starting trying to lead it in the screen it switched again and by the time i noticed and panned back to try to locate it again, it had disappeared. The whole thing lasted about 16 seconds.
