Red-shouldered hawks are slightly smaller then red-tails, with a length of around 17" and a wing span of around 40" compared to 19' and 49' respectively for the red-tail. They are found through out the eastern portions of the US, except for one subspecies that lives in California. Minnesota is on the north west border of their range so they are not that numerous here. Mostly we see them in the summer with the majority of the population in this area migrating south to the south eastern states or Mexico, although I have seen them here on occasion during milder winters. Like the red-tail, they are ambush hunters. They often sit on a favorite perch watching for unsuspecting rodents, lizards, amphibians, small mammals, or birds to come by and then they drop down on them.
