Red-shouldered Hawks return to the same nesting territory year after year. One Red-shouldered Hawk occupied a territory in southern California for 16 consecutive years.
"Buteo" is latin for hawk, while "lineatus" means "stipes" and refers to the tail.
The oldest-known Red-shouldered hawk was 22 years old.

Found in deciduous woodlands, often near rivers and swamps. They build stick nests in a main crotch of a large tree.
Mostly small mammals, lizards, snakes, and amphibians. They also eat toads, snakes, and crayfish. They occasionally eat birds, sometimes from bird feeders; recorded prey include sparrows, starlings, and doves.
Hunt by soaring over forests or perching on tree branches or utility wires. Its call, a rising kee-rah is a distinctive sound of the forest. They hunt small mammals, amphibians, and reptiles either from perches or while flying.
Both sexes help build the nest, or refurbish a prior year’s nest. Stick nests are about 2 feet in diameter and lined with bark, moss, and lichens.
