Spotted
The Biak Leaf Warbler is a small, relatively plain warbler with olive-green upperparts and a paler underside. It is an endemic species, confined to a single island.
Where to spot
Inhabits forests and dense scrub exclusively on Biak Island, off the coast of New Guinea.
How to spot
Listen for its unique song and calls, which will be the primary identification method given its subtle appearance. Observe its rapid foraging movements through vegetation.
When to spot
Observable year-round in its highly restricted island habitat. Most active and vocal during the local breeding season.
This warbler is an example of island endemism, where a species evolves in isolation on an island, leading to unique characteristics.
