Ducks – The Adorable and Friendly Birds. Have you ever watched ducks or fed them at a pond or lake? Then you know that ducks are adorable and almost friendly. If they see you with food, they’ll follow you or even peck at you! Ducks are found in every part of the world, except Antarctica. These water fowl are expert swimmers and divers. Their feathers are designed to keep them warm. Ducks can see well underwater. Ducks eat grain, seeds, nuts, fruit, insects, water plants and even small fish. Source: Easy Science for Kids
