Rainbow Lorikeet Beats the Beauty of Twitter Bird? | Polymerize

The image of rainbow have been reflected on bird?

The Rainbow Lorikeet (Trichoglossus haematodus) is unmistakable with its bright red beak and colourful plumage. Both sexes look alike, with a blue (mauve) head and belly, green wings, tail and back, and an orange/yellow breast. They are often seen in loud and fast-moving flocks, or in communal roosts at dusk.

The Rainbow Lorikeet is a medium sized parrot, with the length ranging from 25–30 cm (9.8-11.8 in) in size, and has a wingspan of about 17 cm (6.7 in). The weight varies from 75–157 g (2.6–5.5 oz). It is a species of Australasian parrot found in Australia, eastern Indonesia (Maluku and Western New Guinea), Papua New Guinea, New Caledonia, Solomon Islands and Vanuatu.

In Australia, it is common along the eastern seaboard, from Queensland to South Australia and northwest Tasmania. Its habitat is rainforest, coastal bush and woodland areas. Several taxa traditionally listed as subspecies of the Rainbow Lorikeet are increasingly treated as separate species.

The Rainbow Lorikeet appears to have benefited from artificial feeding stations and prolific-fruiting and flowering trees and shrubs. The Rainbow Lorikeet mostly forages on the flowers of shrubs or trees to harvest nectar and pollen, but also eats fruits, seeds and some insects. The Rainbow Lorikeet is found in a wide range of treed habitats including rainforest and woodlands, as well as in well-treed urban areas.
 
Rainbow Lorikeets are true parrots, within the Psittacidae family in the order Psittaciformes. The Rainbow Lorikeet has often included the Red-collared Lorikeet (T. rubritorquis) as a subspecies, but today most major authorities consider it separate.

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, but also larger and more powerful birds such as the Australian Magpie.


The Rainbow Lorikeet was accidentally released into the southwest of the state of Western Australia from near the University of Western Australia in the 1960s and they have since been classified as a pest. Rainbow Lorikeets can also be found in New Zealand, particularly around the Auckland area. New Zealand's Department of Conservation has declared them a pest and is implementing methods to control and eradicate them. Many fruit orchard owners consider them a pest, as they often fly in groups and strip trees containing fresh fruit. In urban areas, the birds create nuisance noise and fouling of outdoor areas and vehicles with droppings. In Western Australia, a major impact of the Rainbow Lorikeet is competition with indigenous bird species. This includes domination of feeding resources, and competition for increasingly scarce nesting hollows. Birds such as the Purple-crowned Lorikeet Glossopsitta porphyrocephala and Carnaby's Black-Cockatoo Calyptorhynchus latirostris are adversely affected or displaced.
