Swarm of ufos over Los Altos

Walking down my driveway, facing N/nw, I just happened to look up and saw what I thought was a large flock of birds circling, but seemed very high I could not make out size or type of bird. Than I began to notice that they would go from a dark to light color, but it was not reflective of sun, most of group was circling clockwise, but either side would turn whitish, not just group at “9 o’clock” position as if that how angled in turn, the 3 o’clock side would also go white.

I pulled out my phone to record, and continued watching and the objects were fading in/out, then after about 2 minutes they all vanished. I went to watch the video and stupid me didn’t record!!! I did see a very high altitude plane fly over, maybe over 20,000 ft (lots of planes fly over to sfo, that pattern puts at 6000 over my house, so this plane much higher) but the object were definitely below this plane.
