Nestling, with the down still on the back of the head, flanks, and crissum. The 

 colours of the plumage resemble those of the adult, but are lighter. The feathers of the 

 back are more broadly margined with light grey, as also are those of the uropygium. 

 The upper wing-coverts, both greater and median, are margined with grey, and the 

 feathers of the wings and tail are lighter than in the adult. On the other hand, the 

 yellow of the feet and tarsi is much darker (Buller, Birds Neiv Zeal., Suppl., I., p. 114). 



The description is taken from the typical specimen in the British Museum, and the 

 Plate is drawn from the same bird.
