Luzon (Heriot) Mindanao (Steere Exp.). Japan and Formosa. 



"Adult. Differs from G. melanolophus in its deep vinous-chestnut 

 head, which has a little shade of blackish on the forehead only ; the mantle 

 is browner, and the upper surface generally never seems to be free from 

 dusky vermiculatious ; axillars black and rufous instead of black and 

 white, and no white tips to the outer primaries. Length, 457; culmen, 

 39; wing, 259; tail, 94; tarsus, 63. 



"Young. Differs from the adult in being browner and more uniform 

 on upper mantle and back, but with the wings much freckled with rufous- 

 buff; crown dusky blackish, inclining to dark vinous on the neck. The 

 young bird differs from the young of 0. melanolophus by the rufous tips 

 to the primaries. 



"The description of the young bird is taken from a bird procured by 

 Mr. Ringer at Nagasaki, which still retains some of the nestling down 

 on the head. Full-grown birds, exactly similar in plumage, are in the 

 collection from Luzon and Ayala in Mindanao. 'Bill green, culmen 

 black; legs and feet green; iris yellow/ (Moseley.)" (Sharpe.)
