摘要: An overview of changes to the distribution and numbers New South Wales birds was considered in relation IBRA bioregions, using data from Birds Australia's first second national bird atlases (Atlas 1, 1977 - 1981 Atlas 2, 1998 2001). Reporting rates, adjusted for survey effort, were compared 347 species. Of these, 184 species (53%) showed no change between two atlases, 83 (24%) recorded more frequently during 80 (23%) less 2. This represents a greater proportion declining NSW with whole Australia one previous study found that 15% 422 had declined nationally. 139 woodland tested, 33 similar broader pattern all (23%). Woodland represented 41% NSW, 43% increasing 38% showing atla...
