Old World Warblers (Sylviidae)

Large-billed Reed-warbler (Acrocephalus orinus) - HBW 11, p. 626

French: Rousserolle à grand bec German: Großschnabel-Rohrsänger Spanish: Carricero Picudo
Other common names: Hume’s (Large-billed) Reed-warbler

Taxonomy: Acrocephalus orinus Oberholser, 1905, Himachal Pradesh, India.
Known only from type specimen, and an individual captured in Mar 2006. Has been suggested that it represents an isolated population of A. stentoreus, or an aberrant A. dumetorum; recent re-examination of morphology and mitochondrial DNA, while showing specimen to be similar to latter, nevertheless supports treatment as a separate species. Monotypic.

Distribution: N India: known from type locality near Rampur, in Sutlej Valley (Himachal Pradesh). Very recently, a bird trapped in SC Thailand.
