CHONBURI — 17 May 2026, Thailand’s Khao Kheow Open Zoo has successfully hatched a Greater Adjutant chick for the first time in the country, marking a major milestone in wildlife conservation after the species disappeared from Thailand’s natural habitats more than 40 years ago, officials said.
Natural Resources and Environment Minister Suchart Chomklin said the successful hatching reflected the dedication and expertise of Thai wildlife conservation staff, veterinarians and animal keepers working under the Zoological Park Organization of Thailand and Khao Kheow Open Zoo.

Narongwit Chotchoy, director of the zoo in Si Racha district, said the chick was hatched from eggs laid by the only remaining breeding pair held at the facility.
Because the species typically lays only one or two eggs each year and has a low hatching success rate, zoo staff removed the egg for artificial incubation and hand-rearing in what officials described as a “life-saving operation” to improve the chick’s chances of survival.
Officials said the chick was the first Greater Adjutant successfully bred by Khao Kheow Open Zoo under the Zoological Park Organization of Thailand. It was also described as the first successful hatching by a member zoo of the World Association of Zoos and Aquariums and the South East Asian Zoos and Aquariums Association.

The zoo is now the fourth facility in the world officially recognised for successfully breeding the species in captivity, following Bang Phra Waterbird Breeding Station in Thailand, Assam State Zoo in India and Angkor Centre for Conservation of Biodiversity in Cambodia.
Suchart said the achievement represented an important step in Thailand’s efforts to conserve endangered wildlife and restore threatened animal populations through long-term research and breeding programmes.
