I have heard several people mention that the area around Half Moon Bay is a great place to see raptors. About a week ago, I drove up there and spent a few hours trying to photograph them. I only saw a couple of raptors that afternoon and this was one of them. It was a generally uncooperative afternoon weather wise with it being almost overcast (hence the white background), and they weren't getting that close.
