Detailed explanation-1: -They sometimes poke a stick or a twig into an ants’ nest or termite mound to catch insects to eat. The insects crawl onto the stick or grab it with their pincers. Then the chimp pulls out the stick and nibbles off the insects. Some chimpanzees have learned to use stones and pieces of wood like hammers to crack nuts.

Detailed explanation-2: -Learned behavior comes from watching other animals and from life experiences. By watching their mother, baby ducks learn how to avoid danger and to know what is good to eat. This is an example of learned behavior.

Detailed explanation-3: -Behavior. Chimpanzees are highly social. They live in communities of several dozen animals, led by an alpha male and his coalition of male allies. Research has shown that male and female chimps have individual personalities, with females being more trusting and timid.

Detailed explanation-4: -Wild chimpanzees commonly use sticks to fish for termites, ants or honey. This ability seems to be socially transmitted to juveniles by their mothers across generations.

Detailed explanation-5: -Chimpanzees are sophisticated tool users with behaviours including cracking nuts with stone tools and fishing for ants or termites with sticks. These chimpanzees not only use these sticks to fish out their meal, but they in fact build their own ‘tool kits’ to do so, as observed in the Republic of Congo.
