The component of bird community was recorded in 163 times survey,totally 654.4 hours,at the Temple of Heaven,Beijing from May 2003 to Dec.2006. A total of 130 species,belonging to 38 families of 13 orders,were recorded.The bird diversity is highest in May,lowest in August.However,the evenness index is highest in Winter and Spring,and lowest in Summer.Correspondingly,the dominance index is highest in summer and lowest in Spring.Compared with the bird list got in the 60s to 80s of last century,the dominant bird species has decreased to 3 species,i.e.Tree Sparrow (Passer montanus),Azure-winged Magpie (Cyanopica cyana) and Common Magpie (Pica pica).The seasonal change of bird component is correlated with the duration of bird migration and with the population size changes of resident-bird seasonally.A successfully breeding of Silky Starling (Sturnia sericeus) has been reported in this paper.
