Since the beginning of the Cockatoo Care program in 2001, a lot of valuable feedback has been received through thousands of observation cards, frequent sighting forms, phone calls and letters on sightings of black cockatoos throughout Western Australia, mainly from the south-west. Sightings have been reported by many members of the community, including tourists, members of many groups including the Friends of the Bibbulmun Track, Mingenew Primary School and Water Corporation rangers. The WA Museum has incorporated these sightings into an observation database, which has provided baseline data on the distribution of each species, habitat preferences, flock size and the movements of the cockatoos.

Thank you to all who have helped record sightings of the black cockatoos.
