Endangered natural treasure: The Helmeted Hornbill depicted here is the only type of hornbill with solid casque that is left.
IPOH: For the past decade, a conservation group that conducts expeditions to the Royal Belum-Temengor forest complex has found, to its dismay, that it has spotted just about 20 Helmeted Hornbills.
The number of these critically endangered birds has not shown any signs of an increase, said Ecotourism and Conservation Society Malaysia (Ecomy) president and chief executive officer Andrew Sebastian.
