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 investigates how the Forest Red-tailed Black-cockatoo has adapted to the urban environment. It focuses on the range expansion into urban areas, the use of novel food resources, 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.
