Abstract
Surveys for the endangered Star Finch (Neochmia ruficauda clarescens (Hartert)) were conducted in the early wet season on Cape York Peninsula. We found Star Finches in only two grassland vegetation types. Most sightings were on unburnt islands of grass and saltbush on tidal saltpans where the birds were feeding solely on the seeds of the annual grass Xerochloa imberbis R.Br. Some individuals were also found among tall perennial grasses further inland where they fed on the first seed production of the new wet season. Xerochloa imberbis is probably a critical food source and saltpans a critical habitat for survival of this population of Star Finches during the early wet season.
Acknowledgments
Special thanks go to the many people who contributed to the success of the expedition, including our Aboriginal collaborators Paddy and Lindsay Bassani and fellow birdwatchers Eda Addicott, John Allen, Alex Anderson, John Augustyn, Peter Bannink, Belinda Bannink, Michael Barnett, Phillip Brook, Greg Czechura, Russell Cumming, Helen Dawson, Kay Dorricott, Ian Fox, Alastair Freeman, Sue Gould, Rod Thorn, Trish Hammond, Laurie Knight, Petch Manopawitr, Geoff McLaughlin, Marty McLaughlin, Dan Murphy, Robert Powell, Phillip Rankin, Carol Schmidt, Suzanne Sellwood, Ian Sinclair, Rita Sinclair and Kelvin Williams. Funding for the work was provided by the Cape York Natural Heritage Trust and the Cooperative Research Centre for Tropical Savannas with logistic support from the Queensland Parks and Wildlife Service. Birds Australia helped coordinate volunteers and Bob Smith flew us in his helicopter and also participated in counts. Thanks are also given to the Lama Lama people of Princess Charlotte Bay and the Rirrmerr Corporation for support of the research on their traditional lands. Geoff Mills created the first set of random points and Peter Horne’s patient GIS expertise was invaluable for producing maps and extracting vegetation data. Useful comments were received from four anonymous referees.
