Hong Kong scientist uses nest boxes to protect endangered cockatoos
Only 1,200 to 2,000 of these birds remain worldwide, with one-tenth residing in Hong Kong.
Astrid Andersson, a researcher at the University of Hong Kong, describes the city as home to one of the largest remaining wild populations.
Habitat loss and illegal trade threaten the survival of these rare birds.
The cockatoos rely on natural tree hollows for nesting, but 80% have disappeared due to typhoons and urban development.
Andersson has designed nest boxes to mimic these hollows, hoping to boost breeding success.
She plans to install around 50 boxes across Hong Kong to support the declining population.
Without intervention, she warns the birds may struggle to replace lost individuals.
The nest boxes also provide a rare opportunity to study their reproductive behaviour.
Hong Kong's cockatoos are believed to descend from escaped pets rather than native populations.
The city's urban parks have become an unexpected sanctuary for these birds.
Residents often mistake them for common parakeets, unaware of their endangered status.
Yellow-crested cockatoos are distinct from their Australian sulphur-crested relatives.
In Hong Kong's bird markets, the endangered species is discreetly sold at high prices.
Trade in wild-caught yellow-crested cockatoos has been illegal since 2005.
Sharon Kwok Pong of Hong Kong Parrot Rescue suspects a black market is operating.
She calls for stricter enforcement to protect the species from illegal trafficking.
Andersson has developed a forensic test to detect illegally captured birds.
The test analyses dietary traces to determine if a bird was recently taken from the wild.
In their native Indonesia, poaching and habitat destruction have decimated populations.
Hong Kong's cockatoos may hold genetic diversity lost elsewhere.
Andersson suggests they could serve as a backup population for conservation efforts.
The survival of these birds now depends on both scientific intervention and public awareness. - AFP

Hong Kong scientist uses nest boxes to protect endangered cockatoos
HONG KONG: Above the bustling streets of Causeway Bay, a conservation effort is underway to save the critically endangered yellow-crested cockatoo.

Godzilla's scars: How the Hiroshima and Nagasaki bombings continue to influence Japanese art
TOKYO - From Godzilla's fiery atomic breath to post-apocalyptic anime and harrowing depictions of radiation sickness, the influence of the nuclear bombings of Hiroshima and Nagasaki runs deep in Japanese popular culture. In the 80 years since the World War II attacks, stories of destruction and mutation have been fused with fears around natural disasters and, more recently, the Fukushima crisis. A volunteer pushes paper lanterns out onto the Motoyasu River after they were released by visitors to mark the 80th anniversary of the world's first atomic bomb attack, in the city of Hiroshima on August 6, 2025. (Photo by Richard A. Brooks / AFP) Classic manga and anime series "Astro Boy" is called "Mighty Atom" in Japanese, while city-levelling explosions loom large in other titles such as "Akira", "Neon Genesis Evangelion" and "Attack on Titan". "Living through tremendous pain" and overcoming trauma is a recurrent theme in Japan's cultural output "that global audiences have found fascinating", said William Tsutsui, a history professor at Ottawa University. The US nuclear bombing of Hiroshima on August 6, 1945 left around 140,000 people dead. It was followed days later by the bombing of Nagasaki that killed around 74,000 people. Some poetry "portrays the sheer terror of the atomic bomb at the moment it was dropped", but many novels and artworks address the topic indirectly, said author Yoko Tawada. "It's very difficult for the experience of the atomic bomb, which had never existed in history before, to find a place in the human heart as a memory," she told AFP. Tawada's 2014 book "The Emissary" focuses on the aftermath of an unspecified terrible event. She was inspired by connections between the atomic bombs, the 2011 Fukushima nuclear disaster and "Minamata disease" -- mass mercury poisoning caused by industrial pollution in southwest Japan from the 1950s. The story "is less of a warning, and more a message to say: things may get bad, but we'll find a way to survive", Tawada said. Godzilla's skin Narratives reflecting Japan's complex relationship with nuclear technologies abound, but the most famous example is Godzilla, a prehistoric creature awakened by US hydrogen bomb testing in the Pacific. "We need monsters to give a face and form to abstract fears," said professor Tsutsui, author of the book "Godzilla on My Mind". "In the 1950s, Godzilla fulfilled that role for the Japanese -- with atomic energy, with radiation, with memories of the A-bombs." Many people who watched Godzilla rampage through Tokyo in the original 1954 film left theatres in tears, he said. And "it's said that the special effects people working on Godzilla modelled the monster's heavily furrowed skin after the keloid scars on the survivors of Hiroshima and Nagasaki." In the nearly 40 Godzilla movies released since, nuclear themes are present but often given less prominence, partly to appease American audiences, Tsutsui said. Even so, the series remains hugely popular, with 2016 megahit "Shin Godzilla" seen as a critique of Japan's response to the tsunami-triggered Fukushima disaster. 'Black Rain' "Black Rain", a 1965 novel by Masuji Ibuse about radiation sickness and discrimination, is one of Japan's best-known novels about the Hiroshima bombing. But the fact Ibuse was not an A-bomb survivor is part of a "big debate about who is permitted to write these stories", said Victoria Young of the University of Cambridge. "How we talk about or create literature out of real life is always going to be difficult," she said. "Are you allowed to write about it if you didn't directly experience it?" Nobel-winning author Kenzaburo Oe collected survivor accounts in "Hiroshima Notes", essays written on visits to the city in the 1960s. "He's confronting reality, but tries to approach it from a personal angle" including his relationship with his disabled son, said Tawada, who has lived in Germany for four decades after growing up in Japan. "The anti-war education I received sometimes gave the impression that Japan was solely a victim" in World War II, she said. "When it comes to the bombings, Japan was a victim -- no doubt" but "it's important to look at the bigger picture" including Japan's wartime atrocities, she said. As a child, illustrations of the nuclear bombings in contemporary picture books reminded her of depictions of hell in historical Japanese art. This "made me consider whether human civilisation itself harboured inherent dangers", making atomic weapons feel less like "developments in technology, and more like something latent within humanity". - AFP

Heat extremes drive major declines in tropical birds
Climate change-driven heat extremes have wiped out 25-38 per cent of tropical bird populations since 1950. 17 Aug 2025 07:00pm This photograph shows fallen bird feathers at the Parc Floral in eastern Paris on July 29, 2025. (Photo by Martin LELIEVRE / AFP) SYDNEY - Climate change-driven heat extremes have wiped out 25-38 per cent of tropical bird populations since 1950, Xinhua reported, based on a study involving Australian scientists. The study found that while shifts in average temperature and rainfall have some influence, the biggest climate threat to birds, particularly in tropical regions, comes from exposure to extreme heat, according to an analysis released Tuesday on the University of Queensland website. A pelican flies past birds perched on dead cypress trees in coastal waters in lower Plaquemines Parish on August 05, 2025 in Venice, Louisiana. - AFP photo Australian and European researchers analysed over 3,000 bird populations from 1950-2020, using weather data to separate climate impacts from human pressures such as habitat loss, in a dataset of 90,000 observations from all continents, it said. The research, published in Nature Ecology & Evolution, confirmed the work of other climate scientists showing extreme heat events have increased dramatically over the past 70 years, especially near the equator. Birds in tropical regions are now experiencing dangerously hot days about ten times more often than they did in the past, researchers have found. Surviving birds may suffer lasting damage, including organ failure and reduced breeding success, as extreme heat lowers body condition, limits foraging, stresses eggs and chicks, and can cause dehydration or nest abandonment, the study showed. Researchers warned that even remote, protected tropical forests untouched by humans are seeing heat-driven bird declines, with climate impacts outweighing direct human pressures. Given that nearly half of all bird species are found in tropical regions, the findings signal a major threat to global biodiversity and urge urgent emission cuts and habitat protection to conserve species. - BERNAMA-XINHUA More Like This
