Which one of the following makes a tool with a stick to scrape insects from a hole in a tree or a log of wood?
(a) Fishing cat
(b) Orangutan
(c) Otter
(d) Sloth bear
The correct answer is (b) Orangutan.
Orangutans are known to use sticks to extract insects from holes in trees. They will often break off a small branch and use it to probe the hole, then lick off any insects that are stuck to the stick. This is an example of tool use, which is a relatively rare behavior in the animal kingdom.
Orangutans are also known to use leaves to wipe their faces and to use sticks to scratch their backs. They are highly intelligent animals and are capable of learning new behaviors through observation and imitation.
