2023 Eastern Rosella $1 1oz Silver Proof Coin
John Gould was an English ornithologist and artist who published a number of monographs on birds including this illustration of a family of Eastern Rosella, small birds native to the Australian content.
His identification of the birds nicknamed ‘Darwin’s finches’ played a role in the inception of Darwin’s theory of evolution by natural selection.
The eastern rosella is 30 cm (12 in) long. It has a red head and white cheeks. The beak is white and the irises are brown. The upper breast is red and the lower breast is yellow fading to pale green over the abdomen. The feathers of the back and shoulders are black, and have yellowish or greenish margins giving rise to a scalloped appearance that varies slightly between the subspecies and the sexes. The wings and lateral tail feathers are bluish while the tail is dark green. The legs are grey. The female is similar to the male though duller in colouration and has an underwing stripe, which is not present in the adult male.
