The Japanese Leaf Warbler is a small, rather slender warbler with olive-green upperparts and pale underparts. It is a migratory species known for its persistent, often monotonous song.
Where to spot
Breeds in coniferous and mixed forests in parts of Northeast Asia (e.g., Japan, Sakhalin), wintering in Southeast Asia.
How to spot
Listen for its characteristic, somewhat monotonous, accelerating song. Scan the mid to upper canopy for its active movements while foraging for insects.
When to spot
Best observed during the breeding season (late spring to summer) when it is most vocal. Also during migration periods (spring and autumn).
