This paper reported results of field observation on foraging habitat selection of the wintering Blacknecked Cranes(Grus nigricollis)in Caohai,Guizhou of China. Data of the foraging habitat selectin were analyed by the Friedman statistical method.Five types of foraging habitats of Black-necked Cranes,i.e.,sedge meadow ,shallow water marsh,corn field,vegetable field and gras and,were identified in Caohai. The sedge meadow was the Most preferable one of BLack-necked Cranes while the farmland the least.The preferential sequenee of the other habitats varied site bv site.Human activities in Caohai were one of the major factors influencing habitat use and selectiola by crances.Some suggestions were also put forward on the habitat proteetioa for the wintering Black-necked Cranes.
