A medium-sized hawk, the Red-shouldered hawk has bold black-and-white flight feathers and rusty shoulder patches. Seen in flight from underneath, especially when lit from the sun, its wings show a translucent 'window' near the tips.
It relies on perches for hunting and is closely affiliated with wooded wetlands and riparian bottomlands.
In the breeding season this hawk is found in moist woodlands with at least a few deciduous trees. It prefers riparian bottoms, especially those near shallow wetlands or open meadows. In winter, it may use more open lands such as found in the Rogue and Willamette valleys, depending on perches available for hunting.
