Ashy-bellied White-eye
Zosterops citrinella
Small songbird with bright yellowish upperparts and white “goggles.” Most subspecies have gray underparts; subspecies “unicus” of Sumbawa and Flores has a yellow belly. Compare with other white-eyes in various parts of their range; note present species combination of dark iris and yellow back. Inhabits a wide range of different wooded habitats across its range, including coastal scrub, mangroves, inland forests, and forest edge. Forages actively in small to medium-sized flocks, sometimes mixing with other species. Can be quite common on small islands. Twittering song is bright but unremarkable. Most frequently given call is a somewhat variable high-pitched, descending “djee.”

Narrow-billed Antwren
Formicivora iheringi
Long-tailed antwren with white flanks, unmistakable within its restricted range. Males are dark gray with a black bib. Females are olive-brown above and cinnamon below with two buff wing bars. Found in deciduous forests, where it forages from the understory to middle levels, usually alone but sometimes loosely accompanying mixed-species flocks. Songs a long series of clear “tiuw” notes.

Upcher's Warbler
Hippolais languida
A medium-sized, gray-brown warbler that looks very similar to other species. Note the rather stout bill and broad dark tail. Smaller and browner than Olive-tree Warbler and larger than Eastern Olivaceous Warbler. Wing panel is not as prominent as that of Olive-tree Warbler. Breeds on scrubby hillsides and river valleys; occasionally in flatter lowlands. During non-breeding season, found in a variety of wooded or brushy habitats. Sings from prominent perches—a repetitive, rapid mix of musical and scratchy phrases. Call is a harsh "chak."

Kofiau Monarch
Symposiachrus julianae
A medium-sized bird of lowland forest interior on Kofiau. Slate-gray above, white below, black face and silver-gray bill. Undertail is white with a black band in the base and thin black line at the tip. Forages actively at all levels. Unlikely to be mistaken. Northern Fantail has a dark chest band and Black-browed Triller has white marks in the wing. Voice, buzzy notes similar to Spot-winged Monarch.
