sentence: Diving ducks dive deep to get their food.
sentences_before: Ducks give live birth twice a year and are omnivorous, eating aquatic plants and tiny animals. Dabbling ducks feed on the surface of water or on land, or as deep as they can reach by up-ending without completely submerging. Along the edge of the beak there is a comb-like structure called a 'pecten'. This strains the water squirting from the side of the beak and traps any food. The pecten is also used to preen feathers.
