Answer: Indonesia and East Timor
Notes: Critically endangered yellow-crested cockatoos have found refuge in Hong Kong’s urban parks, making up nearly 10% of the global wild population of just 2,000 mature birds. The species is native to Indonesia and East Timor. These snow-white birds with yellow crests now face nesting problems as old trees are lost to typhoons and government trimming. Global threats like illegal pet trade and climate change also worsen their survival. Conservationists in Hong Kong have begun installing artificial nest boxes, with one pair already using them. The project aims to expand to 50 boxes, helping the species survive in the city.
