Red-Shouldered Hawks are extremely common in the U.S. east of the Mississippi River, as well as in California. They're beautiful birds. They can be distinguished from Red-Tailed Hawks by their smaller size and black and white banding on the tail. Red-Shouldered Hawks also typically have a rufous mark on their shoulders (hence the name). One thing I love about them is they seem unafraid to hunt when I'm near by. I've seen them catch frogs, snakes, and even squirrels. And they have a lovely call that alerts me to their presence so I can go find them and photograph them. When perched, tt seems to me that they often call right before they fly, so I can be ready to catch them in flight.
