Female. " Slightly smaller than the male, but similar in plumage, 

 excepting that there is little or no olive tinge on the head and upper 

 surface, less chestnut on the breast, while there are chestnut spots 

 on the under tail-coverts." 



Yoimg. " General plumage lighter, and the underparts whitish ; 

 the green gloss which pervades the plumage of the upper parts in 

 the adult almost entirely absent ; hind head and nape dull cinereous 

 brown ; breast obscurely spotted with dusky and brown, sometimes 

 barred with chestnut at the insertion of the wings ; under tail-coverts 

 dull rufous-brown " (Buller). 



Fledffling. " The colours are those of the adult, but paler. The 

 long, soft, white down is still present on the throat and lower side 

 of the cheeks, whilst broken or irregular lines of the same proceed 

 from the frontal base and from the sides of the upper mandible, and 

 become scattered beyond the eyes. The dull olive-green down, with 

 long disunited filaments, still adheres to the crown and other portions 

 of the upper surface, being most pronounced immediately above the 

 tail. The bill is slaty brown (in the dried specimen), the terminal 

 points of both mandibles and the serrated edges being dull yellow " 

 (Buller). 



Yotmgin down. " Bill horn-colour, lightest on the lower mandible, 

 unguis rosy at the point ; membranous appendage slaty black, well 

 overlapping the lower mandible, furnished with lamellae along its 

 basal half, which work against the finely-serrated sides of the com- 

 pressed basal half of the lower mandible : body covered with thick 

 down, longest on the back ; upper surface dull green, brightest on 

 the back ; over and behind the eye irregular streaks of white ; 

 under surface white ; wings and upper part of thighs brownish : 

 tail green above, at each side a patch of chestnut ; under surface of 

 the tail chestnut ; legs and feet yellowish flesh-colour " (Potts).
