The crane hawk is the sole member of the genus Geranospiza and is notable for its unusually flexible, double-jointed tarsi, which let it reach into tree cavities and bromeliads to extract prey. It shows striking convergent evolution with the African harrier-hawk, which has a similar foraging adaptation. Its long, reddish legs and broad white tail band make it distinctive in flight.
