Pearl-bellied White-eye Zosterops grayi

Justification

Distribution and population
Zosterops grayi is restricted to the Banda Sea Islands Endemic Bird Area, Indonesia, where it occurs on Kai Besar only. It is moderately common.

Population justification
The population size of this species has not been quantified, but it is described as moderately common in all wooded habitats.

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.

Ecology
This species inhabits a variety of forest and scrub habitats.

Threats
This species may be vulnerable to forest loss within its small range, although little is known of the current status of habitats on Kai Besar.

Conservation Actions Underway
None are known.

Conservation Actions Proposed
Monitor population and habitat trends on Ka Besar. Conduct ecological studies to determine habitat requirements and response to forest disturbance or fragmentation. Protect significant areas of forest on Kai Besar in community-led multiple use areas.
