This is a picture from way back in December. I was doing housework and I looked out the kitchen window, and there was a bird of prey sitting in the mesquite tree, eating a smaller bird. I snapped a few quick pictures through the window, because I wasn't about to go outside and disturb his/her meal!
Apparently the Harris hawks nest in Reid Park, which is just a few blocks away from my house, so it's not unusual to see them hunting pigeons in our neighborhood. It was surprising to see one enjoying lunch in my yard, however. When I'd previously seen piles of feathers below that tree, I naturally assumed that they were the work of one of the stray cats.
I've also seen a raccoon under the same tree. And someone on the other side of the park from us saw a ring-tailed cat. Javelinas and coyotes also occasionally show up inside the city. This is the reason why I like to keep all my pets indoors -- well, that and the 100 degree heat, which doesn't stop the dogs from wanting to play outside all day.
