【Abstract】 226 species and 8 subspecies of birds have been collected from Chengdu by Sichuan University and Chengdu Zoo since 1954. In addition, there are 6 species from reports of other authors. Therefore, the total number of birds in Chengdu has come to 232 species ane 8 subspecies.Among the species and subspecies, there are 46 residents, 34 summer visitors, 81 winter visitors and 79 migrants.Here, most of the breeding birds are common to farmland. The birds in winter are more abundant and complex than those in summer. The seasonal composition of birds has more resemblance to that of southern China.Analysing 80 breeding species from the above mentioned, the Oriental elements occupy 67.5%, and only 16.3% to the Palaeartic. Many Oriental breeding species and subspecies here are the same with Southeastern China. The eccology of birds in this avifauna are chiefly marked to prefer a warm condition.From the above results and from the material of historical geology, palaeontology, palae-oclimatology, we consider that this avifauna chiefly derived its origin from Southeastern China.更多还原
