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. Its habitat is rainforest, coastal bush and woodland areas. Six 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, Tasmania,Auckland, New Zealand and Hong Kong.
Description: The rainbow lorikeet is a medium-sized parrot, with the length ranging from 25 to 30 cm (9.8 to 11.8 in) including the tail, and 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 and colorful. The head is deep blue with a greenish-yellow nuchal collar, and the rest of the upper parts (wings, back and tail) are green. The chest is orange/yellow. The belly is deep blue, and the thighs and rump are green. In flight a yellow wing-bar contrasts clearly with the red underwing coverts. There is little to visually distinguish between the sexes.Juveniles have a black beak, which gradually brightens to orange in the adults.
The markings of Trichoglossus moluccanus resemble those of the coconut lorikeet (Trichoglossus haematodus), but with a blue belly and a more orange breast with little or no blue-black barring.
Behaviour: Rainbow lorikeets often travel together in pairs and occasionally respond to calls to fly as a flock, then disperse again into pairs. Rainbow lorikeet pairs defend their feeding and nesting areas aggressively against other rainbow lorikeets and other bird species. They chase off not only smaller birds such as the noisy miner and the little wattlebird, but also larger birds such as the Australian magpie.
Breeding: In southern Australia, breeding usually occurs from late winter to early summer (August to January). Elsewhere in Australia, breeding has been recorded in every month except March, varying from region to region due to changes in food availability and climate.Nesting sites are variable and can include hollows of tall trees such as eucalypts, palm trunks, or overhanging rock.One population in the Admiralty Islands nests in holes in the ground on predator-free islets.Pairs sometimes nest in the same tree with other rainbow lorikeet pairs, or other bird species.The clutch size is between one and three eggs, which are incubated for around 25 days. Incubation duties are carried out by the female alone.Rainbow lorikeets are mostly monogamous and remain paired for long periods, if not for life.
Status: Overall, the rainbow lorikeet remains widespread and often common. According to the annual Birdlife Australia census, it is the most commonly observed bird in Australia.t is therefore considered to be of least concern by BirdLife International. The status for some localised subspecies is more precarious, with especially T. h. rosenbergii, the Biak lorikeet (which possibly is worthy of treatment as a separate species), being threatened by habitat loss and capture for the parrot trade.
