For one, the high population density in Balinsasayao shows that government programs implemented since 2004 are working, Paguntalan says. In NNNP, which covers more than 70,000 hectares (173,000 acres), the group encountered fewer birds because it has the least number of tall, mature trees to host flocks of tarictics. “It also indicates the main habitat preference of the Visayan tarictic hornbill.”. Gone are the wild elephants, rhinoceroses, and tigers of the Philippines. The Visayan tarictic hornbill is classified as endangered on the IUCN Red List, while the Philippines’ environment department has bumped it up to critically endangered on the national red list.

Conducted from March 2014 to December 2019, it involved 232 sampling areas, which Paguntalan’s team visited more than 600 times over 62 field days. The group then combined these encounters — both visual encounters and records of the hornbills’ notorious raucous calls — to calculate hornbill density using DISTANCE, a widely accepted computer program for species estimates. “But now, a visit for a day would ensure an encounter with a hornbill and if one is very lucky, see a flock of close to 50 hornbills.”. “We were also surprised by the overwhelming support from the local government units and the warm welcome and enthusiasm of the local communities participating in the event made it even more inspiring,” Paguntalan says.
