Afghanistan's fledgling conservation agency moved Sunday to protect one of the world's rarest birds after the species was rediscovered in the war-ravaged country's northeast. The remote Pamir Mountains are the only known breeding area of the large-billed reed warbler, a species so elusive that it had been documented only twice before in more than a century. On Sunday, Afghanistan's National Environment Protection Agency added the large-billed reed warbler to its list of protected species, which was established only last year. Mustafa Zahir, the agency's director-general, acknowledged the difficulties of trying to protect wildlife in a country preoccupied with the Taliban insurgency. But Zahir said the discovery of the large-billed reed warbler provided some welcome positive news. The large-billed reed warbler was first documented in India in 1867 but wasn't found again until 2006 — with a single bird in Thailand. The Afghan environmental agency also added 14 other species to the protected list on Sunday. It now includes 48 species including the rare snow leopard, the Asiatic cheetah and the markhor, a type of wild goat with large spiral horns.
