Scientist uses nest boxes to help save endangered yellow-crested cockatoos in Hong Kong.
A Hong Kong scientist, Astrid Andersson, is using nest boxes to help save the endangered yellow-crested cockatoo, with only 1,200 to 2,000 left globally.
The nest boxes mimic natural hollows for nesting and aim to boost the birds' population in Hong Kong, which hosts one of the largest remaining wild populations.
The project also seeks to observe the birds' reproductive behavior, never comprehensively studied before.
Habitat loss and a potential black market for the birds threaten their survival.
