Food habits of red-bellied squirrels Callosciurus erythraeus were researched in the forest mostly composed by Crypotomeria fortunei in Hongya county, Sichuan province. Direct observation and rumen content analysis were conducted. The squirrels fed on 23 plant species belonging to 14 families, such as fruits of Rubus columellaris and Castanea mollissimaCamellia oleifera flowers, and barks of Crypotomeria fortunei and Cunninghami lanceolata. There were 28 plant species in Hongya confirmed foraged by squirrels with literatures in former years. The ratio of fruit and seed in stomach contents was 75.60%±0.53% in autumn, 63.32%±0.69% in summer, 34.02%±0.43% in winter and 14.35%±0.71% in spring. The differences were significant (P<0.05). The bark in stomach contents was significantly lower in summer (7.32%±0.50%) and autumn (8.30%±0.87%) than that of winter (28.13%±0.72%) and spring (28.71%±0.84%) (P<0.05). The results indicated that the red-bellied squirrels foraged more barks in winter and in spring was probably because of the shortage of fruits and seeds in those two seasons.
