Even his median coverts (wrist of wing) are pigmented. This is akin to one of the Japanese Harlequin peacocks -all white green peafowl hybrids with coloured ocelli, median coverts and sometimes facial stripe and forehead/crest. But this is better because this bird is the hue of the inside of a pink seashell. I can't wait to see what happens with him when you put him on supplements to bump his colour. He may well be iridescent mother of pearl if maintained on a supplemented diet through to his next moult.
