Field Identification

11·5–12 cm. Has fairly wide white eyering interrupted at front by big blackish spot; forehead, forecrown, lores and area under eyering black, merging posteriorly into yellowish-olive of rear crown and upperparts; flight-feathers and tail feathers blackish-brown, margined yellowish-olive; golden-yellow below; merging on side of breast into olive of upperparts; iris reddish-brown; bill black; legs yellow. Differs from Z. luteirostris in having relatively longer tail, black (instead of yellow) bill, more black on crown and brighter coloration. Sexes alike. Juvenile undescribed.

Systematics History

Sometimes treated as conspecific with Z. luteirostris, but differs in morphology and DNA (1). Monotypic.

Subspecies

Monotypic.

Distribution

Ranongga, in WC Solomon Is.

Habitat

Primary forest, scrub, gardens, secondary forest.

 

Movement

Not known.

 

Diet and Foraging

No information.

 

Sounds and Vocal Behavior

Sings often, especially at dawn, a short simple but unpredictable series of c. 9 staccato down- and/or upslurred notes. Contact call “cheu”, slightly louder and more disyllabic than that of other white-eyes.

Breeding

No information.

 

VULNERABLE. Restricted-range species: present in Solomon Group EBA. Small and declining population confined to a single island, where it is the only white-eye present. True population size perhaps underestimated; this species considered common by some ornithologists, and may be better reclassified as Near-threatened. On the other hand, if it is found to have a severely fragmented range, and if current local demand for timber persists, its conservation status may have to be upgraded in future to that of Endangered.
