A survey of the literature on the use of a particular foot to hold food by Australian parrots suggests that most of the few species that have been studied are left-footed. Most, but not all, Glossy Black- Cockatoos
Calyptorhynchus lathami observed have been left-footed. I present some field observations on the footedness of this species; all birds but one were left-footed. I conclude that the right-footed bird was unusual, and that the species is primarily left-footed.
Most Glossy Black-Cockatoos have been reported to husk Allocasuarina cones from the stem end. I suggest that the husking of cones from the free end may be a distinguishing characteristic of the discrete population of Glossy Black-Cockatoos inhabiting inland New South Wales.
