Swainson's Hawk is a raptor and a medium-sized member of the Buteo genus. It broadly overlaps in size with the Red-tailed Hawk (B. jamaicensis), a related species found as a breeding resident almost throughout North America. Swainson's Hawk is on average a little shorter in length, 43–56 cm (17–22 in) long, and weighs a bit less, 0.5–1.7 kg (1.1–3.7 lb). However, Swainson's Hawk has a slightly longer wingspan at 117–137 cm (46–54 in), with more slender, elongated wings, than the Red-tailed Hawk. Female Swainson's Hawks, at an average weight of 1.15 kg (2.5 lb), are somewhat larger and heavier than males, at an average of 0.81 kg (1.8 lb). Among standard measurements, the wing chord is 36.2–42.7 cm (14.3–16.8 in), the tail is 18.5–23.4 cm (7.3–9.2 in), the tarsus is 6.2–8 cm (2.4–3.1 in) and the bill (from the gape) is 3–3.5 cm (1.2–1.4 in). In flight, Swainson's Hawk holds its wings in a slight dihedral; it tips back and forth slightly while soaring. There are two main color variations. Over 90% of individuals are light-morph; the dark morph is most common in the far west of the range: (Wikipedia)
