Join us for the Great Cocky Count

The Great Cocky Count is a citizen-science survey, and the biggest single survey for black-cockatoos in Western Australia. In the lead-up to the Count each year, we ask people to keep an eye out for roost sites, which helps us plan the upcoming Count. Then, on one evening each autumn, volunteers monitor known roost sites and count black-cockatoos as they arrive in the evening. Records submitted from across the South West provide a snapshot of black-cockatoo populations, helping us quantify changes in their numbers.

Where can I take part in this survey?

The Great Cocky Count takes place in south-western Western Australia — south-west of a line between Geraldton and Esperance — on a single night in autumn. Citizen scientists can help in the lead-up to the Count by locating night roosts (places where the black-cockatoos gather to sleep at night).

Simply register to take part in the Great Cocky Count and you’ll receive instructions and a site to survey. Please be aware registrations close on Sunday 12 March, 3 weeks prior to the Great Cocky Count. 



Help us learn more about black-cockatoos by joining the Great Cocky Count

Black-cockatoos live across a large area, so it’s difficult to get an accurate record of how many there are in the wild. By working with citizen scientists in the Great Cocky Count, we are able to get a snapshot of where black-cockatoos are located, giving us a better idea of their numbers.

The Great Cocky Count started as a survey for Carnaby’s Black-Cockatoos, focusing on their roost sites around Perth, but in recent years it has expanded to include Baudin’s Black-Cockatoos and Forest Red-tailed Black-Cockatoos as well, at sites right across the South West.

Take part in a Great Cocky Count workshop before the Count

Great Cocky Count workshops are held at a number of locations around Perth and the South West in the lead-up to the Great Cocky Count. During these workshops, participants learn about black-cockatoo biology, ecology, behaviour and threats. Most importantly, they learn how the Great Cocky Count works and what to record during the survey.

Upcoming workshops will be listed here, as well as on the BirdLife WA Facebook page and through the BirdLife WA e-news.

Please be aware registrations close on Sunday 12 March, 3 weeks prior to the Great Cocky Count. 

The Great Cocky Count is supported by the Alcoa Foundation, and forms part of the Alcoa Community Black-cockatoo Recovery Project.
