Looks like a cherry headed conure.
If you haven’t seen it, I recommend the 2003 documentary “The Wild Parrots of Telegraph Hill.” Set in San Francisco.

Thanks. I travel to San Francisco frequently and they’ve definitely taken up residence there - they are all over, not just on Telegraph Hill - squawking and carrying on as they do.
I pointed them out to my family who promptly got out binoculars and were shocked that there were “parrots in San Francisco” of all place.
I love watching them and had a few in my own backyard - they are definitely not native to Southern California.
