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.

The 2021 Great Cocky Count (GCC) is on Sunday, March 28 at sunset (approximately 5.30-7.00pm in Perth). Please be aware registrations close 3 weeks prior to the GCC (Sunday 7 March).
