【Abstract】 We surveyed wild bird diversity at Beijing Zoo from January 2012 to December2017. Using line transect and point-count sampling methods,we recorded a total of 86 bird species. This accounted for 25% of the 351 bird species recorded to date in the Beijing area. Whitecheeked starling( Sturnus cineraceus),Eurasian magpie( Pica pica),azure-winged magpie( Cyanopica cyana),large-billed crow( Corvus macrorhynchos) and tree sparrow( Passer montanus)were dominant species. Residents,summer visitors, winter visitors and passage migrants accounted for 26%,22%,10% and 42% of recorded bird species,respectively. We recorded redwhiskered bulbul( Pycnonotus jocosus) and Chinese hwamei( Garrulax canorus) as escaped cagebirds. Fifty-three insectivores accounted for 62% of all records. Five bird species were categoryⅡstate-protected wildlife species,viz.
