Because over 60% of their diet is fruit (based on averaging thousands of observations), they are considered frugivores; however, orangutans also will eat young leaves (approximately 25% of their diet), flowers and bark (approximately 10%) and insects, mainly ants, termites, pupae, and crickets (approximately 5%). Wild orangutans are selective but opportunistic so if there is an emergency of tasty and nutritious insects, they may feed all day on them. Likewise, if fruit and insects are unavailable, they may eat bark, leaves and foods of lower nutritional value to satisfy their hunger. Wild orangutans learn to eat hundreds of different food types as youngsters by observing their mother and being allowed to take food from their mother's mouth or hands.
