The female is called a hen , the male is called a drake , and the young are called ducklings . Males are brightly colored, having a green head, a white collar, and a bright yellow bill. Females are mottled brown with a brown bill. Mallard ducks have a varied diet. They eat insects, worms, frogs, snails, slugs, small shellfish, grasses, and other plants that grow near shore.
Nests are usually on the ground in dense undergrowth.
The female cares for the young. Without our visitors' support, Enchanted Learning would soon be off-line.
