Three large crows fly w/nw. The lower rearward one, is missing all of its tail and possibly part of its hindquarters, and there are holes near where the wings join the body. I have never seen anything like this. Shortly afterward, a huge raptor with (on its wings: a bright area near the outer edge, then a dark area at it) crosses their path high above, sailing w/sw on the updrafts from Sutro mount.
