Hawk Owls are middle-sized, long-tailed owls with striking black and white markings. Their pale faces are bordered with black edges, including eyebrow-like markings which over their bright yellow eyes give them a piercing gaze. In flight they may resemble a large-headed Sparrowhawk. They can be distinguished from Tengmalm’s Owls by their larger size, longer tails, and a pale patch across the top of their breast. Their legs have blackish-brown claws and are covered with feathers. Their beaks are yellow.
