'World's least known bird' found breeding in Afghanistan

Researchers for the Wildlife Conservation Society and Sweden's Gothenburg University said they had found the breeding area in the remote and rugged Wakhan Corridor of north-eastern Afghanistan that has escaped the worst effects of war.

They used field observations, museum specimens, DNA sequencing, and the first known audio recording of the species to find the birds and verified the discovery by capturing and releasing almost 20 birds, the largest number ever recorded.

A preliminary paper on the finding appears in BirdingASIA, describing the discovery in Afghanistan as "a watershed moment" in the study of this bird.

The first specimen of the large-billed reed warbler was discovered in India in 1867 but the second find was not until 2006 in Thailand.

"Practically nothing is known about this species, so this discovery of the breeding area represents a flood of new information on the large-billed reed warbler," said Colin Poole of WCS's Asia Program, in a statement.

"This new knowledge of the bird also indicates that the Wakhan Corridor still holds biological secrets and is critically important for future conservation efforts in Afghanistan."

The find came after Robert Timmins from the WCS was conducting a survey of bird communities in the area; Kazinform cites China Daily.
