    Abstract

    The size of prey taken by Powerful Owls Ninox strenua, the relative densities (abundance) of small versus large arboreal marsupials in eucalypt forests, the lack of asymmetrical ears in Ninox owls, and the male’s habit of roosting on dead prey during the day may be clues to understanding ‘Normal’ Sexual Size Dimorphism in large Ninox species, the inverse of the ‘Reversed’ Sexual Dimorphism found in most owls, hawks and falcons.
