Blyth’s Reed Warbler

Indian warbler “lost” for 139 years makes spectacular return—in Thailand and the UK
Ornithologists across the world are celebrating with the news that a wetland bird that has eluded scientists ever since its discovery in India in 1867 has been refound. Twice.
The Large-billed Reed-warbler is the world’s least known bird.
A single bird was collected in the Sutlej Valley, Himachal Pradesh, India, in 1867, but many had questioned whether it was indeed represented a true species and wasn’t just an aberrant individual of a common species.
But on 27 March 2006, ornithologist Philip Round, Assistant Professor in the Department of Biology, Mahidol University, was bird ringing (banding) at a wastewater treatment centre (the royally initiated Laem Phak Bia Environmental Research and Development Project) near Bangkok, Thailand.
“Although reed-warblers are generally drab and look very similar, one of the birds I caught that morning struck me as very odd, something about it didn’t quite add up; it had a long beak and short wings,” said Round.
“Then, it dawned on me—I was probably holding a Large-billed Reed-warbler. I was dumbstruck, it felt as if I was holding a living dodo.”
“I knew it was essential to get cast-iron proof of its identity. I took many photographs, and carefully collected two feathers for DNA analysis, so as not to harm the bird.” …
“This remarkable discovery gives Indian ornithologists an added incentive to continue our search for the Large-billed Reed-warbler in India,” said Dr Asad Rahmani, Director of the Bombay Natural History Society.
“Like the discovery of Bugun Liocichla last year in Arunachal Pradesh, it shows us just how much we still have to learn about our remarkable avifauna.” …
But, in a further twist to this remarkable tale, six months after the rediscovery, another Large-billed Reed-warbler specimen was discovered in the collection of the Natural History Museum at Tring, in a drawer of Blyth’s Reed-warblers (Acrocephalus dumetorum) collected in India during the 19th Century.
Once again, Professor Staffan Bensch confirmed the identification using DNA.
“Finding one Large-billed Reed-warbler after 139 years was remarkable, finding a second—right under ornithologists’ noses for that length of time—is nothing short of a miracle,” said Butchart.
The second specimen is from a different part of India and is bound to fuel debate as to the whereabouts of more Large-billed Reed-warblers.

Researchers for the Wildlife Conservation Society have discovered for the first time the breeding area of the large-billed reed warbler—dubbed in 2007 as “the world’s least known bird species”—in the remote and rugged Wakhan Corridor of the Pamir Mountains of north-eastern Afghanistan: here.
