Oreomystis maculata (Cab.)- 

 Fift}' years have passed since Cabanis described and named 

 this species as occurring on Oahu — the most populous island of 

 the group. Previous to the present record its nest and eggs had 

 never been taken, or at least had not been reported. This species 

 seems to be fairly well restricted in its range to the forest belt of 

 the Waiauae mountains. They are exceedingly industrious birds,

found associated together in small unorganized flocks of a half 

 dozen individuals, which usually keep within hearing distance of 

 the rather plainly whistled cherk! which is uttered by first one, 

 then another, as they carefully search the bark of the tree trunks 

 and the larger limbs for inse(5ls, which form the staple article of 

 their food. However, the}^ occasionally extend their feeding 

 grounds so as to include the smaller branches and twigs, where, 

 barring the difference in the notes uttered by the two species, they 

 might easily be mistaken for C. chloris, which they resemble quite 

 closely at a short distance.
