Established in 1962, Khao Yai National Park is the first national park of Thailand. It is also regarded as an ASEAN Heritage Park and UNESCO World Heritage Site because of its pristine forest and the abundance of wildlife. Because of the high variety of birds including globally threatened species and regional endemics that have been reported within the national park such as Masked Finfoot (Heliopais personatus), Silver Oriole (Oriolus mellianus) and Coral-billed Ground-cuckoo (Carpococyx renauldi), Khao Yai National Park is also regarded as one of the Important Bird Areas (IBAs) by BirdLife.
Khao Yai Bird Census is an annual activity organised by BCST to monitor the trends and populations of birds within Khao Yai National Park. It is carried out by bird experts, BCST members and volunteers who are interested. Data collected during the census is provided to the national park as well as the public.
