Justification:
|
The large-billed reed warbler Acrocephalus orinus is known only from one specimen, collected in the Sutlej Valley near Rampoor, Himachal Pradesh, India in 1867. Its taxonomic status has been uncertain for more than a century, and it was treated as synonymous with clamorous reed warbler Acrocephalus stentoreus. However, a recent study re-evaluated the status of this taxon, and confirmed its specific status based on morphology and mtDNA evidence. Its morphology, with a relatively rounded wing, suggests that it represents a resident or short-distance migrant. Given the lack of information, and the previous confusion over the status of this taxon, it is best treated presently as Data Deficient.
