My wife and I were having lunch yesterday when we heard a loud noise on our kitchen skylight glass. I looked up, noticed a shadow and my first thought was that it was a raven, as they are frequent visitors in our neighborhood. But then it became apparent that it was a hawk, who had spotted our lunch spread out on the table below. We were having (among other things) leftover ribs, and the bones and uneaten ribs were in a couple of dishes on the table below the skylight.
The hawk was staring right at us and the food and was very determined to get through the (inch thick) skylight glass. I'm glad that we weren't eating in the backyard! The pictures taken with an iPhone and are somewhat blurry since the fog was very heavy that morning and the skylight was still quite wet.
We frequently see/hear hawks and other wildlife in Golden Gate Park which is only several blocks away from our house. But we have never experienced this before, although we have to bungee tie our trash and compost bins to guard against nightly visits by raccoons.
