| Abstract: | The food habit of red squirrels ( Sciurus vulgaris ) was studied by analyzing the contents of the stomachs in the forest regions of Daxing'an Mountains and Xiaoxing'an Mountains from 1999 to 2000. The results show that seeds and fruits were the most important food of red squirrels accounting for 78% of total foods. The next main food was fungi which contained 10% of total food. The little ratio of buds, leaves, barks and vascular material were found in the food of red squirrels, which made up from 5% to 8% of the stomach contents. Red squirrels also were found to be occasional predators of insects and other small animals in summer. There were significant difference in food habit among different seasons and so do between the two areas. |
