Red-shouldered hawks are large, broad-winged hawks with a relatively long tails and heavy bodies. They show reverse sexual size dimorphism, meaning that females are larger than males.
The diet of red-shouldered hawks consists primarily of small mammals, the largest of these being rabbits and squirrels. Other food items include reptiles and amphibians, such as snakes, toads, frogs and lizards, small birds and large insects. Crayfish are important prey for red-shouldered hawks in some regions.
Red-shouldered hawks search for prey while perched on a treetop or soaring over woodlands. When they sight prey, they kill it by dropping directly onto it from the air. They may cache food near their nest for later consumption.
Red-shouldered hawks use sight and hearing to hunt successfully. They do not hunt by smell. Some key characteristics that make red-shouldered hawks especially well-adapted to hunting are sharp eyesight and broad wings. The shape and structure of red-shouldered hawks’ wings allow them to soar effortlessly for extended periods of time searching for prey. The hawks’ large eyes are situated to look forward. Although this means that the birds must turn their heads in order to keep prey in view, the orientation of their eyes affords them excellent depth perception. The high concentrations of light-sensitive cone cells in red-shouldered hawks’ eyes also provide good resolving power and very sharp vision.
