Justification

Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population:

Population

The global population size has not been quantified, but the species is reported to be scarce in the lowlands, fairly common from 800 m-1,450 m and uncommon at higher elevations in New Britain, very scarce in lowland areas and abundant at high elevations in New Ireland and fairly common to common in Manus (Coates 1990).

Bismarck White-eye:

The Bismarck white-eye or black-headed white-eye (Zosterops hypoxanthus) is a species of bird in the Zosteropidae family. It is endemic to the Bismarck Archipelago in Papua New Guinea, where is occurs in New Britain, New Ireland and a number of smaller islands. It is sometimes considered to be the same species as the black-fronted white-eye of the mainland of New Guinea. The species is found in forests, forest edges, secondary forest, gardens and plantations, generally in hill and mountain areas and more rarely down to sea level.

The species has a black face, dark olive neck, back and wings, and olive rump with a black tail (paler in some subspecies), and bright yellow undersides. The white eye-ring is bright but incomplete, broken at the front. The plumage of the male and female are similar.
