Critically endangered cockatoos take refuge in Hong Kong as conservationists race to save them

Critically endangered yellow-crested cockatoos recovered an unexpected sanctuary among Hong Kong’s towering skyscrapers, but for illustration their quality neighbours, they now look problem uncovering a spot to telephone home.

Native to Indonesia and East Timor, nan snow-white birds, their crests flashing for illustration yellowish crowns, squawk done nan municipality parks of nan Asian financial hub. They dress up astir 10 per cent of nan species' world chaotic population, which numbers only up to 2,000 mature birds.

Research shows nan city’s cockatoo organization has stagnated arsenic nan birds, which unrecorded successful character cavities, are losing earthy nesting spaces successful aged trees owed to typhoons and authorities character trimming for nationalist safety. That's adding to world pressures connected cockatoos, specified arsenic nan forbidden pet waste and acquisition and ambiance change.

Hong Kong's conservationists person stepped successful pinch a solution: installing artificial nest boxes that mimic these earthy hollows.

Astrid Andersson, a postdoctoral interrogator astatine nan University of Hong Kong who led nan project, said a brace of birds had already settled successful a nest container her squad fixed onto a character connected her campus, nan city’s oldest university. She intends to instal 10 boxes by year's extremity and yet boost that fig to 50 successful nan adjacent fewer years crossed Hong Kong Island.

“And past they tin proceed to unrecorded successful nan city,” she said.

Pet waste and acquisition and residence nonaccomplishment push type successful Indonesia to nan brink

Once wide crossed land chains from cardinal to eastbound Indonesia and East Timor, nan yellow-crested cockatoo has vanished from galore islands and clings to endurance connected others.

The International Union for Conservation of Nature says arsenic overmuch arsenic 90 per cent of nan organization is thought to person vanished since 1978, chiefly owed to trapping for nan pet trade.

Weak enforcement of a 1994 export prohibition by Indonesia has allowed nan waste and acquisition to persist, including targeting chicks. In 2015, Indonesian constabulary arrested a man connected suspicion of smuggling astir 20 birds by stuffing them wrong h2o bottles.

Deforestation from farming and logging is different problem. Indonesia mislaid 107,000 quadrate kilometres of its original tropical rainforest betwixt 2002 and 2024, an area astir nan size of Iceland, accounting for astir a 3rd of all character screen loss during that time, according to Global Forest Watch.

Climate alteration is making things worse. Rising temperatures barren retired forests, leaving them much susceptible to fires. Many birds unrecorded connected volcanic islands, wherever eruptions tin spark wildfires successful nan parched landscapes.

“The fires are humongous,” said Bonnie Zimmermann, head of nan Indonesian Parrot Project, a nonprofit organisation.

Hong Kong vertebrate marketplace income raise concerns

The chaotic cockatoos successful Hong Kong’s municipality parks could beryllium from escaped aliases released pets, Andersson said. One municipality fable says they descended from pet birds released by a British politician earlier he surrendered to invading Japanese troops successful 1941. Hong Kong, a erstwhile British colony, returned to Chinese power successful 1997.

Hong Kong bans commercialized trading successful wild-caught cockatoos, but allows captive-bred income for operations registered nether nan Convention connected International Trade successful Endangered Species of Wild Fauna and Flora, aliases CITES. However, location is nary specified breeding cognition registered successful nan city.

In August, a three-month-old chick was priced astatine 14,000 Hong Kong dollars (€1,533) successful nan city’s vertebrate market.

A 2017-2018 study by Andersson recovered 33 cockatoos for sale, triple nan number of birds imported since 2005. They could beryllium from location breeding, trafficking from overseas aliases Hong Kong’s chaotic population, nan assemblage said successful a statement.

Andersson has developed a forensic trial to thief separate betwixt those who unrecorded successful nan chaotic and those bred successful captivity, and she hopes it tin beryllium applied successful nan marketplace 1 day.

Many Hong Kongers do not cognize nan birds are critically endangered. Dreamy Cheung said she was unaware erstwhile she bought her pet, Mochi, successful 2021 for 20,000 Hong Kong dollars (€2,191). She felt anxious aft learning of her intelligent bird’s endangered status, particularly fixed its missing recognition limb ringing and imaginable forbidden origins.

“It's for illustration taking distant personification else’s baby,” she said.

In an emailed connection to The Associated Press, nan Agriculture, Fisheries and Conservation Department said nan authorities was committed to protecting endangered species, pinch regular inspections astatine markets and shops. It has nary grounds of cockatoo poaching successful nan past 5 years, but it will analyse immoderate reports, it said.

It added that it will supply proposal connected vertebrate conservation for immoderate character trimming that whitethorn impact chaotic birds.

Creating abstraction for coexistence

Hong Kong's cockatoos symbolise really humans and wildlife tin coexist successful a highly urbanised environment, said Andersson. Local birds besides whitethorn transportation immoderate chopped familial lineages missing successful their autochthonal range, helping to prolong their familial diversity.

“Hopefully, Hong Kong’s organization will beryllium capable to lend to redeeming this type from extinction," she said.

Her squad plans to usage cameras installed wrong nan nest boxes to cod information astir cockatoo reproductive behaviour, a taxable that has not been extensively studied.

Cockatoos squawked successful nan precocious branches of a character successful a parkland successful nan city's Causeway Bay area arsenic conservationist Harry Wong installed a wood chip-filled nesting box.

Wong tried a akin task a decade agone without success.

This time, watching cockatoos inhabit a nest container astatine nan University of Hong Kong conscionable 2 months aft it was installed, he was excited and surprised.

“We tin create mini things successful nan metropolis that let nan animals who unrecorded present to coexist pinch us,” he said.
