Bird Survey Data, Cumberland Plain SuperSite, 2017

Bird community composition is surveyed along an established 1 km point transect through Cumberland Plain Woodland. Dominant overstorey tree species include Eucalyptus tereticornis, Eucalyptus moluccana, Angophora subvelutina and Melaleuca decora with an understorey including Bursaria spinosa and Acacia parramattensis over a predominately grassy ground storey. Surveys are undertaken quarterly by three or four experienced observers. Surveys commence at first light. Observers walk slowly along the transect in a group and pause for 5 mins at each of 11 locations spaced at 100 m intervals along the transect. Records are made at each point and while walking between points of the presence of any bird species identified from their calls, and for birds sighted and identified visually, records also include the number of individuals, distance from the observers and behaviour. Weather conditions at the time of the survey are also recorded.
