[edit] Taxonomy

Monotypic^[1]

Subspecies macrorhynchus is usually considered invalid^[2]

This taxon is considered a subspecies of Clamorous Reed-Warbler (sensu lato) by some authors^[2]

[edit] Habitat

[edit] Status

The Large-billed Reed Warbler is an enigmatic species and was only known to the world from one specimen collected in Himachal Pradesh in North-western India, until Philip D. Round mist-netted one in Thailand in March 2006.

This image represents the 4th ever recorded bird of this species (one skin of what was thought to be a Blyth's Reed Warbler has since been identified as Large-billed - this was from India in the 19th century).
