摘要：

The diet of the European brown bear (Ursus arctos) was studied in the Cantabrian Mountains, Spain, by analyzing the frequency of occurrence and percent volume of 929 feces collected 1983-1988. Plant material was the predominant food during spring and summer (84.1 and 44.8% of total volume, respectively) until more nutritious foods became available. During autumn and winter, hard mast formed the greatest part of the diet constituting 61.5 and 49.9% of the total volume, respectively. Livestock and wild ungulates were supplementary foods for bears, usually obtained by scavenging rather than predation. Insects were consumed year-round, ranging from 19.5% volume in summer to 0.1% in winter. Remnant deciduous forests and upland creek drainages were prime feeding areas of bears.
