Justification of Red List Category
This species has a tiny range, being restricted to a single island, where it is common. It is likely to be able to withstand some habitat degradation, but would be under severe threat if rates of habitat clearance increased. It is currently considered Near Threatened.
The population size of this species has not been quantified, but it is described as moderately common in all wooded habitats.
The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
Zosterops grayi is restricted to the Banda Sea Islands Endemic Bird Area, Indonesia, where it occurs on Kai Besar only. It is moderately common.
This species inhabits a variety of forest and scrub habitats.
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.
