The Rainbow Lorikeet is very colourful - almost every colour of the rainbow can be found on their feathers. They are not large birds, with a Rainbow Lorikeet's length ranging from 25–30 cm (9.8-11.8 in) in size, and have a wingspan of about 17 cm (6.7 in). The markings of the best known subspecies T. h. moluccanus are particularly striking. The features distinguishing a Rainbow Lorikeet include a dark blue or violet-blue head and stomach, a bright green back, tail and vent, and an orange breast and beak. Several subspecies have darker scalloped markings across the orange or red breast.
