New Species from the Mekong Delta

Nonggang Babbler
Named for the Nonggang Natural Reserve in which it was found, this Sino-Vietnamese bird lives in flocks of five to 10 and flies short distances — but only when frightened. Most of its time is spent foraging for insects that live between rocks. So far, only 30 of these birds have been spotted.
