Chin white. Throat black with more or less white tips (not so conspicu- 

 ous as in the Hawaii species). Breast with some reddish brown. Abdo- 

 men white. 



Intermediate plumage: Similar to that of the young, but showing brown- 

 ish-black in the throat, and more or less white in the wing and tip of tail. 



Juvenile plumage: Above tawny yellowish-brown, most yellowish on 

 sides and back of neck. 



Forehead, lores, chin, throat and chest tawny brownish-yellow. 



Wing-coverts and primaries brown with brownish-yellow edges. Larger 

 wing-coverts sometimes showing white tips, forming a bar less conspicuous 

 than in adults. 



Upper -tail-coverts tawny-brownish-yellow. Under-tail-coverts tawny. 

 Abdomen white. 



The plumages of the female and young differ from the male in the same 

 manner as those of the Kauai species. 



The Oahu species is distinguished from that of Hawaii, with which it 

 was long confused, by its more conspicuous white throat and almost entirely 

 white breast. Seale has given an excellent account of the plumage changes 

 of this species.

Oahu has been more completely despoiled of its native bird life 

 than any other of the larger islands. More of the known Oahu 

 passerine species are extinct than are living today. The Oahu 

 Elepaio is the most abundant of the remaining native birds and is 

 practically the only species commonly seen.
