2010年3―5月，对楚雄市郊（龙江公园、楚雄师范学院、峨碌公园和尹家咀水库）鸟类群落进行直接观察。采用连续取样法采集鸟类取食行为数据，用聚类分析法分别对四个样地的鸟类群落进行集团划分，通过无倾向对应分析（DCA）对鸟类的资源利用特点进行研究。结果表明，峨碌公园的鸟类群落可分为6个取食集团，龙江公园的可分为3个取食集团、尹家咀水库存在3个取食集团、学校的可分为2个，这暗示着植被类型和结构的变化导致鸟类取食集团的数量和结构的差异。DCA分析表明，鸟类取食集团的变化是鸟类对不同生态环境的适应性，主要表现在取食高度、取食位置以及取食方式和取食基层的差异。%The bird community of urban district (Longjiang Park and Chuxiong normal university)and suburban district (Western mountain and Yinjiazui Reservoir )in Chuxiong were directly observed from March to May in 2010 . Focal sampling method was used to observe feeding behaviors of the bird communi-ty,and collect food resource utilization date. Cluster analysis was used to determin the guild structures in the four samples,and Detrended Correspondence Analysis (DCA)to the feeding patterns of the birds. Re-sults showed that the bird community in Elu park could be divided into 6 guilds,3 guilds in Longjiang Park,3 guilds in Yinjiazui Reservoir and 2 guilds in Chuxiong Normal University. This indicated the varia-tion in structure and type of vegetation contributed to the difference of number and structure in birds fora-ging guilds. The result of DCA showed that the variation of foraging guild was adaptive to ecological envi-ronment,and the adaptation was mainly in foraging behavior,especially in foraging height.
