Juvenile is entirely dark brownish, but by four months of age like adult female; immature male as adult female; subadult male variable, like adult female with few feathers of adult male plumage intruding, initially about head, to like adult male with few feathers of female-like plumage remaining; male gains progressively longer central pair of rectrices; in captivity, first traces of adult male plumage acquired at c. 5 years, full plumage after at least a further year or two, two nestlings took three years to acquire completely yellow iris.
