The rainbow lorikeet (Trichoglossus moluccanus) is a species of parrot found in Australia. It is common along the eastern seaboard, from northern Queensland to South Australia and Tasmania. Its habitat is rainforest, coastal bush and woodland areas. Several taxa traditionally listed as subspecies of the rainbow lorikeet are now treated as separate species (see Taxonomy). Rainbow lorikeets have been introduced to Perth, Western Australia; Auckland, New Zealand; and Hong Kong. The rainbow lorikeet is a medium-sized parrot, with the length ranging from 25 to 30 cm (9.8–11.8 in), including the tail. The weight varies from 75 to 157 g (2.6–5.5 oz). The plumage of the nominate race, as with all subspecies, is very bright. The head is deep blue with a greenish-yellow nuchal collar, and the rest of the upper parts (wings, back and tail) are deep green. The chest is red with blue-black barring. The belly is deep green, and the thighs and rump are yellow with deep green barring. In flight a yellow wing-bar contrasts clearly with the red underwing coverts. There is little to visually distinguish between the sexes; however, to a keen observer of their colouring and behaviour, their dimorphism is readily apparent. Juveniles have a black beak, which gradually brightens to orange in the adults. The markings of the best known subspecies T. h. moluccanus resemble those of the nominate race, but with a blue belly and a more orange breast with little or no blue-black barring.[8] Other subspecies largely resemble either the nominate race or T. h. moluccanus, or are intermediate between them. Two exceptions are T. h. flavicans and T. h. rosenbergii. In the rather variable T. h. flavicans the green of some individuals is dull, almost olivaceous, [8] but in others the green hue approaches that typical of the rainbow lorikeet. T. h. rosenbergii is highly distinctive and several features separates it from all other subspecies:
