The Thick-billed Warbler is a large, robust warbler named for its relatively stout bill. It is a migratory species, breeding across East Asia and wintering in Southeast Asia.
Where to spot
Breeds in dense scrub, willow thickets, and forests in eastern Asia (from southern Siberia to northeastern China). Winters in various dense habitats, including mangroves and reedbeds, across Southeast Asia.
How to spot
Search dense vegetation, often near water. Listen for its distinctive, loud, and often explosive song, which is a key identification feature. Its skulking nature means patience is required to get a visual.
When to spot
Breeding season (summer) in its northern range, migration periods (spring and autumn) along its flyways, and winter (late autumn to early spring) in its southern range.

Unlike many warblers that are active songsters in the open, the Thick-billed Warbler often sings from hidden perches deep within dense cover.
