VOA科学技术2022--Bird Sellers Help Rare Bird Return to the Wild

（单词翻译）

With its white feathers and blue skin, the Bali mynah has been sought after by collectors for more than a hundred years.

Their capture for sale along with land loss on the island of Bali, Indonesia, led to the bird being listed as "threatened" in 1988. The International Union for Conservation of Nature moved it to "critically endangered" in 1994. And, by 2001, experts estimated only about six Bali mynahs were living in the wild, with thousands in captivity¹ across the world.

Now, conservationists are hoping to increase the mynah population by working with bird breeders and sellers to release them into the wild.

Population and breeding program

In the 1980s, an organization now called BirdLife International started to work with the government to launch a breeding program for the birds.

Breeders can seek government permits to breed the birds. If approved, they are given mynahs by the government and could keep 90 percent of the baby birds for private sale. The remaining birds are released at West Bali National Park, where they will be closely watched by park officials.

Early mynah releases faced problems. Some birds were infected with a parasite² that often caused death; others were killed by natural predators⁴. Illegal hunting also continued — and the national park's breeding center was even robbed at gunpoint, with nearly 40 birds stolen.

Yet conservation efforts in the last ten years have seen greater success, said Tom Squires⁵ of Manchester Metropolitan⁶ University.

Squires said, "Bird keepers can still keep birds and follow their hobby without causing real problems for wild populations — which is, I think, a lot better than species going extinct in the world." To go extinct means to die off completely.

Community involvement

Agus Ngurah Krisna Kepakisan is head of the West Bali National Park. He believes the creation and spread of villages around the park have led to a successful breeding program. Villagers received help in getting permits and bred Bali mynahs there.

"With the community being the breeders ... they are helping⁷ us to take care of the birds that exist in nature," he said.

Squires noted⁸ that there is clear evidence some released birds have produced young ones. "So that leads me to believe that the population is certainly self-sustaining to an extent," he said.

The breeding program's results can be seen throughout the park, where Kepakisan says 420 Bali mynahs now live.

Conservation efforts have also spread to Tabanan Regency — a three-hour drive from the park. The place is a recent release area for Friends of the National Parks Foundation, an Indonesia-based non-profit that works with breeders to release the birds.

I Gede Nyoman Bayu Wirayudha founded the organization and has worked in Bali mynah conservation for years. He said, traditionally, communities around conservation areas have thought there is no money to be made from them. But the rare birds' presence will help draw tourists and their money like in other parts of Bali where mynahs have been released.

"You need to give something back to the community so they can feel that conservation gives them benefits," he said.

Squires hopes the conservation model could be applied⁹ to other endangered birds in Indonesia such as the black-winged mynah. "For any of the lowland birds affected¹⁰ by the caged bird trade ... this is the sort of approach that's going to be needed," he said.
