(i) Frequency of occurrence (proportion of total scats in which an item was found). Frequency of occurrence = . (ii) Percent of occurrence (number of times a specific item was found as a percentage of all food items found barring Phoenix which is not considered as a conventional food item but is consumed by the tiger to regulate bowel movements).
