Feeding site selection of the Ibisbill (Ibidorhyncha struthersii) was investigated at Daocheng in western Sichuan Province of China from January to March 2010.87 birds were observed; density of birds is 1.24 per km,the average group size is 2.12 ± 0.89.41 used sites and 74 controlled sites were recorded (altitude from 3 715 to 4 200 m).By stepwise discriminant analysis,the key factors relating to feeding site selection of the Ibisbill were stone cover with diameter more than 30 cm,acreage of island,interfering distance,river width and the width of bank.Observations on both foraging and ingestion indicated that the foraging frequency is 18.39±2.36 (n=50) and ingestion success rate is 29.39%±13.24% (n=50).9 kinds of food resource were examined,and sampling method suggested that Ibisbill preyed mainly on caddisfly larvae(Trichoptera)(37.72%±12.96%), stonefly larvae(Plecoptera)(36.36%±6.06%) and crustaceans (17.76%±7.74%).
