Taishan Mountain in central Shandong Province is the highest mountain over the centre and east part of North China, with various kinds of habitat and terrain, it is an important ecological region for the breeding and stopover of birds. We compared the variety of breeding bird species for nearly 30 years based on the results of field surveys and interviews in 1984﹣1988 and in 2013﹣2015 (line transects of the field survey are listed in Table 1). Compared with breeding bird species in the 1980s (13 orders, 35 families, 72 species), we recorded 84 species belonged to 34 families, 11 orders in the 2010s (Appendix 1), with 32 species new and 20 species disappeared. New recorded species are mainly forest and shrub birds, and most of them are oriental species; The disappeared species mainly lived in wetlands, farmlands and grasslands, and most of them are palaearctic and cosmopolitan species. Reasons for the addition and disappearance of breeding bird species are multiple, but the main reason is the changes of area and quality of habitats, and privately buy-and-release animals is another important reason. Our results could enrich the background data of bird community changes, and provide scientific support for bird protection in Taishan Mountain area.
