Medium-sized hawk with long tail and thin wings. Flies with wings held in a V-shape, low over open fields and marshes, listening for rodents lurking below. Distinctive foraging behavior and conspicuous white patch on rump in all plumages. Females and immatures are warm brown. Adult males gray above and whitish below with black wingtips.
