Abstract: We collected 223 sable sacts in study areas in Daxinganling Mountains in three winters from 1991 to 1993 (82 scats in 1991，89 in1992，52 in l993)．Results indicate that winter foods of sables are mainly small mammals (54.1%)，berries and pine nuts(32.4%)，birds (12.5%) and ants (1.0%) . Sables select grey red—backed voles ( Clethrionmys rufocanus )and northern red—backed voles . as main food items 7 prey species of small mammals．The nests are arctic hares (Lepus timidus) and dormant Eutamias sibircus．For birds, sables hunt hazel grouses ( Tetrasles bonasia ) (8.1%)，Eurarian jays (Garrulus glandarius)(0.7%), major tits ( Parus major )(0.5%) etc．There are 2．2% scats contain egg shell segments of small birds．Plant food items of sable are berries of Vaccinium vitis-ideae (20.9%) and pine nuts of Piaus pumila (8.8%) ．Ants are found in scats also (1.0%)．There is not difference for frequencies of food items of sables among years (P>0.05)．We also find that sable precate capercaille (Tetrao parviroastris).Although capture rate of C．rutitus(79.4%)is higher than that of C.rufocanus(2.9%)，food habits results indicate that sables prefer C．rufocanus with larger body to C.rutilus，and avoid eating shrews( Sorex caecutiens)with musky odors.
