Differences from owls
Tawny Frogmouths and owls both have anisodactyl feet – meaning that one toe is facing backwards and the other three face forwards. However, owls’ feet are much stronger than the feet of the Tawny Frogmouth as owls use their feet to catch their prey. Owls are also able to swing one of their toes around to the back (with a unique flexible joint) to get a better grip on their prey. Tawny Frogmouths have fairly weak feet as they use their beaks to catch their prey. Owls eat small mammals, like mice and rats, so their bones are shorter and stronger than those of Tawny Frogmouths which usually hunt smaller prey. Tawny Frogmouths typically wait for their prey to come to them, only rarely hunting on the wing like owls.
Tawny Frogmouth pairs stay together until one of the pair dies. They breed from August to December. They usually use the same nest each year, and must make repairs to their loose, untidy platforms of sticks. After mating, the female lays two or three eggs onto a lining of green leaves in the nest. Both male and female take turns sitting on the eggs to incubate them until they hatch about 25 days later. Both parents help feed the chicks.
