" Iris yellow ; skin of face yellow ; bill grey at the base, 

 black at the tip, greenish about the nostrils ; feet yellow." 



The immature male from Davao is in an interesting stage 

 of plumage : the chest and upper breast being clad with the 

 chestnut and white-spotted feathers of the adult, while the 

 lower breast and belly are in the white plumage of immaturity, 

 conveying the impression at the first glance that the speci- 

 men is a semi-albino. A somewhat older bird from Mt. Apo 

 resembles the adult, but the under wing-coverts are mostly 

 white. As I have already pointed out in the paper quoted 

 above, birds of this species from Mindanao and Basilan 

 are smaller than those from Luzon, and in the present 

 instance the wing-measurements of five specimens vary from 

 12*7 to 13-2 inches.
