Diet and Activity of the Bear Cuscus, Ailurops ursinus, in North Sulawesi, Indonesia.
We studied the daily time budget and feeding activity of the bear cuscus, Ailurops ursinus, in the Tangkoko-Duasudara Nature Reserve, North Sulawesei, Indonesia. Bear cuscuses spent 63.4% of their time resting, and feeding accounted for only 5.6% of their activities. Bear cuscuses fed on 31 species of plants, including 26 identified trees and lianas from 17 fasmilies and 5 unidentified mitletoes. Dietary preference was influenced by availability of young leaves, and bear cuscueses maximized the amount of young leaves in the diet.
