The rainbow lorikeet is a medium-sized colourful parrot found in Australia. Its 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 in colour. 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. The males and the females in this species are similar in appearance and juveniles have a black beak, which gradually brightens to orange in the adults.
