“A dult.—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 G. 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.)
