A Preliminary Study on Bird Resources in Xizhuojiaying,Beijing after Wetland Restoration

From September 2008 to March 2010,4 surveys on bird resources in Xizhuojiaying,Yanqing county,Beijing were conducted after the wetlands were restored.A total of 51 bird species,belonging to 36 genera,22 families,12 orders,were recorded in this area.Of them,15 species were residents,16 summer migrants,15 travelers,and 5 winter migrants.9 species including the whooper swan Cygnus cygnus,Eurasian hobby Falco subbuteo,common kestrel F.tinnunculus,merlin F.columbarius,saker falcon F.cherrug,osprey Pandion haliaetus,black-eared kite Milvus lineatus,hen harrier Circus cyaneus and common crane Grus grus were category Ⅱ national key protected animals.Farmland birds,including the magpie Pica pica,tree sparrow Passer montanus and Eurasian collared dove Streptopelia decaocto were dominant,whereas waterfowls,with a total of 21 species occurring in this wetland,accounted for a small part of the total population.This might be related to the shortage of open water coverage and enough plant shelters in this wetland.
