Reference Cords 1986
Scanning method Each month, for 5-6 days the observer did complete all-day follows, and then a further 2-3 days further later. Rudran's (1978) scoring method was used, this measured the frequency of feeding rather than dietary composition. For plant foods, a new feeding score was recorded for the same combination of monkey, item and plant only if 30 minutes had passed, or if the identity of at least one of the three parameters changed.
