Found on four islands in the Faichuk Group, a group of islands within the Chuuk (Truk) atoll in Micronesia.
A restricted-range species with a very small population. A census in 1985 found 382 birds on Tol South (Mount Winipat), 19 on Onei, 32 on Paata and 93 on Polle. Classified as critically endangered.


This is a monotypic species.
It seems to be structurally and vocally very similar to Golden White-eye.


Native forest. Prefers dense, old-growth and well-developed forest above 400m with the endemic poison tree.


No information on diet for adults. Young birds are fed with insects.
Breeding season in April. One described nest was cup-shaped and made of moss, bark strips and dried grass-like plant fibres. It was placed 20m above the ground in a leaf cluster of a poison tree and contained a single chick.
Nothing known about movements.
