PHNOM PENH: Cambodia is home to fewer than 100 white-winged ducks, out of an estimated global population of just 800.
A recent three-day field survey found only a single individual returning to its roost.
Sam Veasna Conservation Tours, in collaboration with the Wildlife Conservation Society (WCS), conducted a survey of the rare species in areas where they has been previously recorded.
The research took place in the Kulen Promtep Wildlife Sanctuary in Preah Vihear Province from May 21 to 23, according to a statement released by Sam Veasna on Thursday (May 29).
During the fieldwork, two teams — each consisting of five members — monitored the site.
Over the course of the three-day observation, they recorded one duck returning to its roost tree for two consecutive nights.
Unfortunately, it arrived after dark and departed before dawn, making it difficult to observe.
Despite this, the mission confirmed that at least one white-winged duck (Anas scutulata) still returns to its traditional roosting site, underscoring the vital importance of large Chhertheal trees along riverbanks, home to this critically endangered bird.
The ducks inhabit tropical forest areas with slow-flowing rivers and streams, preferring quiet, wetland zones such as seasonal pools and swampy grasslands for foraging.

The statement explained that most of Cambodia's white-winged duck population is found in the north, especially in Preah Vihear.
Their numbers are critically low due to human threats such as illegal hunting and trapping, habitat loss, agricultural and settlement expansion, and notably, very low breeding rates.
Both organisations urged local residents in these regions to stop activities that harm the duck population, emphasising that fewer than 100 individuals remain in Cambodia.
The species is listed as critically endangered on the IUCN Red List.
According to the Ministry of Environment, there are only about 800 individuals left worldwide, with viable populations and breeding activity confirmed in the Kulen Promtep sanctuary.
This species is present year-round in Cambodia. - The Phnom Penh Post/ANN

Three Generations Strong: Bali Zoo's Silvery Gibbon Legacy Grows
From Boris's journey back to the wild to the birth of baby Seruni, Bali Zoo leads efforts to conserve one of Indonesia's rarest primates. BALI, Indonesia, June 16, 2025 /PRNewswire/ — In line with its mission Love. Conserve. Share., Bali Zoo shares a powerful story of hope in wildlife conservation. The silvery gibbon (Hylobates moloch), endemic to Indonesia and classified as Endangered by the IUCN Red List, is not only surviving but thriving through dedicated conservation efforts. This year marks the first birthday of Seruni, a healthy female silvery gibbon born at Bali Zoo in 2024. She is the offspring of Boris's sister. Boris, a male silvery gibbon born at the zoo in 2010, was successfully released into the wild at Situ Patengan, West Java, in 2019. After spending one year at a rehabilitation center, Boris was deemed fit for release. The reintroduction was carried out in partnership with The Aspinall Foundation and Indonesian conservation authorities. 'To have bred an endangered animal, released it into the wild, and now welcome the next generation of its extended family is an extraordinary achievement,' said Emma Chandra, Public Relations at Bali Zoo. 'It shows that our long-term commitment to conservation is working.' Bali Zoo's silvery gibbon family now spans three generations, beginning with parents Koko and Minul (both born in 2000), who raised Boris along with four other offspring including Paris, Syahrini, Cincin, and Dahlia. The arrival of Seruni, born to Boris's sister signals not only successful breeding but also a sustained effort to protect one of Indonesia's most endangered primates. Over the past five years, Bali Zoo has recorded key breeding milestones, including: One silvery gibbon, Seruni (born in 2024) One male Sumatran orangutan (born in 2022) Two male Sumatran elephants (born in 2022 and 2023) Multiple births of Indonesia's endemic and exotic species from 2020 to 2025, including: Javan langur, Yellow-crested cockatoos, Papua wallabies, Timor deer and Spotted deer. Since 2019, Bali Zoo supports the Chainsaw Buyback Program in collaboration with Yayasan ASRI. This initiative helps former illegal loggers transition to sustainable livelihoods while protecting vital forest habitats, particularly for orangutans. About Bali Zoo Bali Zoo is home to over 600 animals and is dedicated to the conservation of Indonesia's endemic wildlife. Located in Gianyar. Bali. Click HERE for more images.

Captive-bred green peafowls naturally reproduce in China
A captive-bred green peafowl is seen at the Weishan Qinghua green peafowl provincial nature reserve in the Bai Autonomous Prefecture of Dali, southwest China's Yunnan Province, May 20, 2025.(Xinhua/Hu Chao) KUNMING (May 28): Four green peafowl chicks were recently hatched naturally in a wild training base in southwest China's Yunnan Province, marking the first successful natural breeding of the captive-bred species in a simulated wild environment and major progress in the country's rewilding efforts for the rare birds. The young birds were discovered in mid-May via camera surveillance at the training base located at the Weishan Qinghua green peafowl provincial nature reserve in the Bai Autonomous Prefecture of Dali. The base was co-founded by the nature reserve, the Kunming Institute of Zoology (KIZ) under the Chinese Academy of Sciences, and the Yunnan Forest Nature Center (YFNC), with a focus on wild training of captive-bred green peafowls. Currently, 11 birds are receiving wild training at the base. May 22 marks International Day for Biological Diversity. Yang Jiawei, an official at the reserve, said captive-bred green peafowls are trained in simulated wild conditions to master survival skills like foraging, predator avoidance and reproduction before they are released into the wild.

He added that, in the next step, the base will assess the peafowls' survival skills and release those qualified into the wild with trackers for monitoring, providing technical support for China's conservation efforts. Lu Lin, who is in charge of wildlife rescue and breeding at the YFNC, said that in 2024, the center in the provincial capital Kunming successfully bred 48 chicks, with the hatching rate surging to 73.85 percent, up from 15 percent three years prior. As of May 22, 12 chicks have hatched from 68 eggs laid this year, with more expected soon. The entire hatching process will be completed within two months. The green peafowl, China's only native peafowl species, is classified as 'endangered' on the IUCN Red List, with a higher extinction risk than giant pandas.

In Yunnan, multiple nature reserves have been established in green peafowl habitats, with 48.1 million yuan (about 6.7 million U.S. dollars) spent on conservation projects like population monitoring and habitat improvement as of 2024, said Li Peng, an official in charge of wildlife protection from the provincial forestry and grassland bureau. Thanks to these efforts, the population of wild green peafowls has risen from less than 500 in 2016 to about 850 today. – Xinhua Green peafowl chicks are seen at the Yunnan Forest Nature Center in Kunming, southwest China's Yunnan Province, May 19, 2025.(Xinhua/Hu Chao) animal species China fauna peafowl
