What the animals are called living on herbs?

Animals that live on herbs are called herbivores.

Here are some examples of herbivores:

* Mammals: Cows, horses, deer, rabbits, elephants, giraffes, goats, sheep, etc.

* Birds: Chickens, ducks, geese, parrots, finches, etc.

* Insects: Caterpillars, grasshoppers, locusts, etc.
