This is a Red Tailed Hawk dining on a squirrel yesterday morning. The Hawk was called in as "injured", since it didn't fly off when someone walked by. I left it alone, since it was fine and just doing what it's supposed to do. I have had people call stuff like this in and want us to "make them go away" so they don't have to see any carnage in their upscale neighborhood.
Makes me want to show up at their house one morning, slap the breakfast out of their mouth, and see how they like it :)
