【Abstract】 Two new records of birds occurred in Beijing are reported. Two flocks of Chinese Bulbul (Pycnontus sinensis sinensis) composed of 38 individuals were found in Hongluosi of Huairou County in September 26—27, 2002. One male Red-winged Crested Cuckoo ( Clamator coromandus ) was observed in Xiaolongmen Wood Farm of Mengtougou District on May 23, 2000. Further surveys indicate that Chinese Bulbul is a resident species of birds in Beijing, the distribution sites include Haidian, Shunyi, Huairou and Fangshan; while Red-winged Crested Cuckoo, a summer visitor, arrives in Beijing in the middle ten days of May and migrates southward in early September. These findings together with the records of Crossoptilon mantchuricum, Ficedula mugimaki, Fringilla coelebs coelebs, F. beijingnica, Phylloscopus sichuanensis since 1990 have increased the bird species living in Beijing from 344 to 351. Habitat restoration and intensive surveys may increase avian species diversity of Beijing.更多还原
