This is a Red Shouldered Hawk that found a hunting spot and didn't want to move from it, which allowed me to get very good photos. If you are approaching a bird like this and you don't want to scare it. Watch it. It will start to give signals of nervousness. Such as shuffling its feet, turning its head back and fourth, flap its wings a little. When ever one of these things happen, freeze. Then move a minute later.
