There is a good deal of individual variation in this bird : in 

 some specimens, apparently adult, the yellow colour of the sides of 

 the head extends only a little under the eyes, so that the lower 

 part of the cheeks is green ; in others the upper part of the cheeks, 

 near the gape, is blue like the forehead and lores ; also as regards 

 the bend of the wing the variation in colour is very great, this part 

 in some being red, in others red and yellow, or mostly yellow.
