Javan White-eye Zosterops flavus
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

Although this species remains abundant in suitable habitat, it has a highly restricted and fragmented range, and is likely to be declining moderately rapidly as a result of habitat loss. It is currently considered Near Threatened, and should be carefully monitored.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Zosterops flavus is restricted to Java and southern Kalimantan, Indonesia, with one record from Sarawak, Malaysia. The population on Java is restricted in range (but apparently very common where it does occur) while recent records from Kalimantan suggest the species might be locally common in mangrove on the south coast.

Population justification
The population size of this species has not been quantified, but it is described as locally common.

Trend justification
Data on trends are lacking, but declines are suspected owing to rates of destruction and degradation of coastal and mangrove forests within the range.

This species occurs in mangroves, coastal scrub, relict coastal forest and scattered trees.

This species is likely to be threatened by the destruction and degradation of mangrove forests and other forest habitats, although further studies are needed in order to determine whether it persists in degraded habitats.

Conservation Actions Underway

Conservation Actions Proposed
Conduct ecological studies to determine the response of this species to habitat degradation and fragmentation. Monitor population and habitat trends throughout the range. Protect significant areas of suitable forest at sites where it is known to be common.
