Rosella(Platycercus Vigors). Parrots belonging to this genus are collectively known as rosellas and all show two plumage characteristics; well-defined cheek-patches and a pronounced “mottling” on the back. Rosellas are medium-sized birds with long, gradated tails. There is a notch in the upper mandible. Male rosellas have noticeably wider, heaver upper mandibles than do female rosellas. In all but one species (icterotis) the rosella sexes are alike in plumage. The white, under wing-stripe is present but is variable according to the species.
There are eight species of rosella. Click on the link below for information on the eight rosella species.
