Marshes dominated by common reed have important socio-economic uses and ecological values.Reed cutting has various impacts on fauna inhabited in reedbed.We studied the impacts of reed cutting on foraging of Reed Parrotbill(Paradoxornis heudei) at Chongxi Wetland Research Center in Chongming Island,Shanghai City,China from January to April 2007. Reed cutting decreased potential food resource of Reed Parrotbill significantly.Reed cutting changed the foraging habitat of Reed Parrotbill,and shifted their foraging place from dead reed shoots to growing reed shoots before they suited Reed Parrotbill to feed on them.Short time after reed cutting,the residual dead reed shoots have an important role for foraging of Reed Parrotbill.And these indicated that keeping some reed patches uncut could facilitate Reed Parrotbill foraging on growing reed shoots and lessen food shortage impacts of reed cutting.
