There are several populations of the Crimson Rosella. Red (crimson) birds occur in northern Queensland, in southern Queensland to south-eastern South Australia and on Kangaroo Island. Crimson Rosellas are normally encountered in small flocks and are easily attracted to garden seed trays. Once familiar with humans, they will accept hand held food. Natural foods include seeds of eucalypts, grasses and shrubs, as well as insects and some tree blossoms.
