In the early winter in January to June, the birds pair off and mate as the '?hi'a plants reach their flowering maximum. The female lays two to three eggs in a small cup shaped nest made from tree fibers, petals, and down feathers. These bluish eggs hatch in fourteen days. The chicks are yellowish-green marked with brownish-orange. The chicks fledge in twenty-four days and soon attain adult plumage. At one time the difference in appearance between adults and young gave rise to the belief that they were separate species. Observations of young birds moulting into adult plumage resolved this confusion.
