Rainbow Lorikeet

(Trichoglossus Moluccanus)

The rainbow lorikeet is a species of parrot common along the eastern seaboard, from northern Queensland to South Australia. 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.

Males and females are all but identical. If you know birds are the same age, the male will be larger, but usually the only way to tell them apart is a DNA test.
As pets they can live up to 25 years, in the wild it is likely that their life span is much shorter (around 10 years).
They are hollow-nesters but are not overly fussy. Rainbow Lorikeets have been seen nesting in palms, in rock crevices and even digging a hole at the base of a tree!
