Rainbow Lorikeet

Description:

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). 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 upperparts (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: Its wing-bars are deep orange (not contrasting clearly with the red underwing coverts in flight), the entire nape is yellow bordered by a narrow red band and the dark blue barring to the red chest is very broad

Habitat:

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 (see Taxonomy).

Notes:

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.[2] 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.[3][13] 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.[13] 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.[13] Birds such as the Purple-crowned Lorikeet Glossopsitta porphyrocephala and Carnaby's Black-Cockatoo Calyptorhynchus latirostris are adversely affected or displaced.[13]
