A public awareness programme, Cockatoo Care, is aimed at focussing attention upon their survival requirements. This is being supported by the Water Corporation, whose forest catchment areas are a vital part of the habitat for these birds. Further information: www.cockatoocare.com and www.museum.wa.gov.au
