Red-tailed Black Cockatoos, with Erika Roper – at the DRB Nats

10 May, 7:15 pm-9:30 pm

Topic: Red-tailed Black Cockatoos and their urban ecology.

The threatened forest Red-tailed Black Cockatoo is endemic to southwestern WA and is an iconic species in the area. Historically restricted to the Jarrah forest, over the past 20 years increasing numbers of Red-tails have moved into urban Perth. Erica’s PhD research investigates why the Red-tails have moved to the city and how they have adapted to this new environment by changing their behaviours.

Erika will incorporate a lot of general natural history about the birds as well as explain her research and its findings. Her talk will cover Red-tailed Black Cockatoo ecology, the urban range expansion, diet and foraging behaviours, communication, and how we can help conserve the cockatoos in a changing world.

Speaker: Erika Roper, ecologist and PhD candidate in the School of Biological Sciences, at the University of Western Australia.

Erika grew up in the Southern Tablelands of NSW with an insatiable curiosity for nature, especially birds. This curiosity has taken Erika all over Australia and the world, and resulted in her settling in Perth to complete her PhD. Erika is currently researching the ecology and behaviour of the forest Red-tailed Black Cockatoo (Calyptorhynchus banksii naso). Red-tails are a threatened species inhabiting a novel environment and Erika is working towards a better understanding of their behaviours and needs, in order to inform management decisions and ensure their presence in the southwest for centuries to come. Erika Roper is due to finish her PhD in May this year.
