According to Joseph Foreshaw in ‘Australian Parrots’ the Red-Tailed Black Cockatoo is found across northern and north-eastern Australia, but occurring in isolated populations across central and southern regions. They are striking birds best described by photographs rather than words. In the short flight of an aviary the red of the cock’s tail fans out in a bold flashing of colour that is something one never gets tired of seeing. We keep the nominate species banksii banksii. They are large birds and are best viewed in aviaries that allow them reasonable flight. We keep them in an aviary 6 1/2 metres long by 2 metres high by 2 metres wide.
