Urban Cockatoos

The traditional habitat of the threatened forest subspecies of the red-tailed black-cockatoo (Calyptorhynchus banksii naso) is in the Jarrah forest of south-western Australia. Since 2000, red-tailed black-cockatoos have occurred increasing frequency in the Perth Metropolitan Area on the Swan Coastal Plain. The heavily urbanised Perth Metropolitan Area lies adjacent to the Jarrah forest, and supports a few remnant patches of Banksia woodland. While it is believed most urban red-tailed black-cockatoos commute daily to the Metropolitan Area, there are several urban populations believed to be resident year round. Urbanisation alters the landscape, causing changes to the availability of resources (e.g. food, water, nests), predation, and the sensory environment (e.g. noise, artificial light). This in turn can lead to behavioural adaptations in animals that reside in urban areas.

This project will investigate how the forest red-tailed black-cockatoo has adapted to the urban environment. It will focus on the range expansion into urban areas, the use of novel resources such as exotic foods, the modification of anti-predator behaviours, and the urban environment as novel habitat for red-tailed black-cockatoos. The findings of this study will provide detailed information on behavioural modification caused by urbanisation, and will increase our understanding of the effect of urbanisation on the forest red-tailed black-cockatoo.

  1. there is a group that apparently regularly visits ECU Mt Lawley campus. I’ve seen them there and will happily search my photo archive for you – although I think on the occasion I saw them was one of the rare times I was without my camera. You could perhaps contact the garden/maintenance people there. they might be able to tell you more.
