Young. Differs from the adult in having the feathers of the head 

 green with white bases, those of the pileum with narrow reddish 

 edges, the feathers of the sides of the head white with green edges,

 from Colombia in never having the feathers of the sinciput or 

 pileum white with red edges ; such feathers occur only on the 

 forehead, the rest of the feathers of the pileum being white, dark 

 greyish towards the tips and edged with black.
