Kiritimati Reed Warbler
Acrocephalus aequinoctialis
A medium-sized, mostly cold gray reed warbler. Dark wing feathers with pale edges give a messy appearance. Found in open areas with scattered trees and dense brush. Most common vocalizations include “cha,” “che,” and “churr” notes.
Black-sided Robin
Poecilodryas hypoleuca
A medium-sized, fairly small bird of lowland and foothill forest interior. Black upperparts, head and marks on the sides of the chest, underparts white up to the bill, thin white eye-brow, wedge below the eye and patch in the wing. Shy and difficult to see. Very similar to Black- chinned Robin and co-occurs in some areas, but Black-sided has black on the sides of the chest, and has a narrower white eyebrow. Heard more often than seen. Voice, a distinctive “wee-chow!”, the second note with an explosive quality.
Gray-green Scrubwren
Aethomyias arfakianus
A small bird of lower montane forest interior. Whitish belly, pale gray head and greenish wing. Pale grayish wash on the chest with faint streaking, offsetting the whitish throat. Actively searches leaves and branches for insects in small groups. Co-occurs at elevations with other scrubwrens including Vogelkop, Pale-billed and Perplexing, but Gray-green has olive rather than warm brown upperparts. Song, a scratchy jumble of notes followed by an up and down “chi-doo! chi-doo! chi-doo!”. Calls, various raspy, nasal notes and chattering.
