Adults appear in perfect and unworn plumage in December and 

 January, when the white spots of the wings and tail are of full size 

 and unworn by attrition ; during the months of April and May many 

 individuals show considerable reduction in the size of the white 

 spots; and, in June, July, and August, some of the spots have entirely 

 disappeared from long wearing and consequent reduction in the size 

 of the feathers. 



Young birds, in first plumage, were obtained from April to No- 

 vember, on Luzon Island. In April and the early summer months 

 the young have the mantle unspotted greenish gray. By November 

 these young birds, although lacking any black on the head or throat, 

 are beginning to acquire, while molting, some large pure white spots 

 on the wings and narrow yellowish white ones on the lower mantle. 



Young of this species, when in their first plumage, have no black 

 on the head; those having black heads are marked adult in the fol- 

 lowing table, although a few of them are doubtless subadult. The 

 measurements presented were taken by Miss Celestine B. Hodges.
