Feature: Zealandia, once a deserted dam in New Zealand, now an asylum for native birds

File photo taken on Sept. 9, 2020 shows a kaka, a native bird to New Zealand at Zealandia Eco-sanctuary in Wellington, New Zealand. In the 1990s, kaka, a native bird to New Zealand, was considered nearly extinct in the main islands of the country. However, Zealandia Eco-sanctuary witnessed more than 1,000 kaka chicks tagged in the past 20 years due to conservation efforts of a re-introduction program. (Xinhua/Guo Lei)
