Green rosella.
The green rosella (Platycercus caledonicus) is a parrot native to the Australian state of Tasmania and some Bass Strait islands. The species was described by the German naturalist Johann Friedrich Gmelin in 1788. At up to 37 cm (14.5 in) long, it is the largest species in its genus. Its underparts, neck and head are yellow, with a red band above the beak and violet-blue cheeks. The back is mostly black and green, and its long tail blue and green. The female has duller yellow plumage and more prominent red markings, as well as a smaller beak. Found in a wide range of habitats with some form of tree cover, the green rosella is predominantly herbivorous, consuming seeds, berries, nuts, fruits, and flowers, but it may also eat insect larvae and insects such as psyllids. Nesting takes place in tree hollows. The green rosella is widespread across Tasmania, but the King Island subspecies has been classed as vulnerable.
