What is the name of this bird?
The "Platycerus Elegans", more commonly known as the "Crimson Rosella" is native to Australia, and generally found in mountains, forests, and gardens.
Earlier names of it, used in the 18th century, are the very descriptive "Beautiful Lory" (used by Joseph Banks) and the "Pennantian Parrot". It should be noted that in this instance the word "Pennantian" is not descriptive, but eponymous, after Thomas Pennant.
The name "Crimson Rosella" was not universally acknowledged by ornithologists until the 1920s.
The bird is roughly 36 cm, or 14 inches long, with the tail its longest feature. Despite the name, only 3 of the 7 subspecies are actually crimson. Interestingly, though there is a vast difference in colouration between the juvenile and adult birds, unlike many bird species, there is relatively little between the female and the male, although the latter is larger with a broader beak.
They are generally monogamous, and, interestingly, subspecies, which can interbreed, seem to produce hardier offspring. Although the population is decreasing, they are not currently considered an endangered species.
