Great Cocky Count

28 March 2021 : 5:30 PM - 28 March 2021 : 7:00 PM

The Great Cocky Count is a long-term citizen science survey and the biggest single survey for black-cockatoos in Western Australia. On one night in autumn, volunteers monitor known roost sites and count black-cockatoos as they come in to their evening roosts.

Records submitted from across the southwest provide a snapshot of black-cockatoo populations, and over time this has helped us quantify the changes in black-cockatoo numbers.

A key aim of this count is to survey as many roost sites as possible. We need your help to make the 2021 count the most comprehensive survey yet. The Great Cocky Count will be on Sunday March 28, 2021 at sunset (approximately 5.30-7pm in Perth). Registrations will open in January  until March 7, 2021.


      Report a roost site:
      Help us to identify more roost sites for both white-tailed and red-tailed black-cockatoos! Roosts are places where black-cockatoos rest at night. Important information on the location of critical roosting habitat is collected through the Great Cocky Count, and is increasing each year. If you know about a night-time roost site, please email or call us about it.
      Register to monitor a roost site for the Great Cocky Count.
      Registrations for the next GCC will open mid-January 2021. If you are not on the list already, please email to go on our Cocky Notes list. This is a bi-annual newsletter and the summer edition will give you the link to register for the GCC.

The Great Cocky Count is supported through funding from The Alcoa Foundation.
