Red-tailed hawk

Red-tailed Hawk plumage can be variable, depending on the subspecies and the region. These color variations are morphs, and are not related to molting.
Though the markings and hue vary, the basic appearance of the Red-tailed Hawk is consistent. The underbelly is lighter than the back and a dark brown band across the belly, formed by horizontal streaks in feather patterning, is present in most color variations. The red tail, which gives this species its name, is uniformly brick-red above and pink below. The bill is short and dark, in the hooked shape characteristic of raptors.They have short, broad tails and thick, chunky wings. The cere, the legs, and the feet of the Red-tailed Hawk are all yellow.
Immature birds can be readily identified at close range by their yellowish irises. As the bird attains full maturity over the course of 3–4 years, the iris slowly darkens into a reddish-brown hue. In both the light and dark morphs, the tail of the immature Red-tailed Hawk are patterned with numerous darker bars
