The reproduction process in rainbow lorikeets is quite complex. It begins by courtship, usually in the spring, which in itself is pretty in-depth. The male rainbow lorikeet, which looks similar to the female, begins courtship by flapping its wings animatedly and moving his legs up and down energetically. If the female is interested and it is time for her to begin breeding, her internal chemistry will be altered. Fertilization is internal, and the female will hatch two-three amniotic eggs at the bottom of their tree hollow. Only the female can sit on the eggs, but the male will bring her food. After 25 days, the eggs will hatch. For the next eight weeks, the fledglings will be cared for by both parents. Then after eight weeks, the fledglings leave the nest with their parents for another two weeks of care. The adults can then start the process all over again, sometimes breeding up to three times in one year. Currently there are about 5,000,000 rainbow species alive.
The picture below on the left shows a four-week old rainbow lorikeet, and it doesn't display the colorful plumage yet. The picture below on the right shows a two-month old rainbow lorikeet. As you can see, its colorful feathers are finally starting to show.
