Briefings

Conservationist Harry Wong installed a nest box for yellow-crested cockatoos at St. Louis School in Hong Kong on September 7, 2026, with biologist Astrid Andersson assisting. The project aims to study the behavior of the city's wild population, which comprises approximately 200 individuals representing about 10% of the global wild population. Genetic analysis by Andersson's team previously revealed unexpectedly high genetic diversity in these feral birds.

Key points

• Harry Wong installed a nest box on a candlenut tree at St. Louis School in Hong Kong on September 7, 2026.
• Astrid Andersson, a biologist at the University of Hong Kong, assisted with the installation and research.

Context

This initiative is part of the HK Cockatoo Watch project, which seeks to protect the city's feral yellow-crested cockatoos. The city hosts the largest wild population of the species outside Southeast Asia, with roughly 200 birds.

Limitations

The evidence is limited to a single event on September 7, 2026, and does not include long-term behavioral data or population trends beyond the initial genetic analysis.
