in age they gradually assume the plumage of the adult, which is not fully accomplished until the 

 second or third year. 



There appears to be so much confusion respecting this bird, that we have thought it best to adopt 

 M. Temminck's name of flaviventris, although we have little doubt that the Psittacus Caledonicus of 

 Lath, as well as most of the other synonyms refer to the same bird.
