Hong Kong’s critically endangered alien cockatoo population
During my PhD with Dingle Lab at HKU, I spent four years researching the city’s introduced, ~150 strong Yellow-crested Cockatoo (Cacatua sulphurea) population, including roost counts, nest monitoring, recording vocalisations, camera trapping, habitat transects, diet analysis and observing interactions with other species. We also conducted bi-weekly surveys of the bird market in order to quantify local trade in this species.
Nest-site competition between introduced/native birds in Singapore
During 2018 and 2019 breeding seasons myself and two research assistants recorded aggressive interactions between bird species (both exotic and native) around cavities in large trees around Singapore. The small, densely populated city has an abundance of birdlife – including hornbills1, introduced cockatoos, kingfishers, dollarbirds, woodpeckers, parakeets… to name but a few of the cavity-nesters that use these hollows for breeding.
Understanding Hong Kongers’ opinion of urban wildlife
Over 120 people living in cockatoo-inhabited areas of Hong Kong have completed an online survey with both multiple-choice and open-ended questions about their experience with the cockatoos, attitude towards them, and opinions on government policy for these birds. The survey is still ongoing, and the results provide interesting insight into how even densely populated urban areas can provide habitat for both humans and wildlife.
