Quick answer
Mallards feed on plants, seeds, insects and invertebrates, adjusting with season, age, and what is abundant in Lakes, rivers, marshes, and city ponds. That label is a preferred pattern, not every item an individual might sample.

Mallard diet overview
Mallards (Anas platyrhynchos) are best summarised as Omnivore (plants, seeds, insects, invertebrates). Anatomy and habitat (Lakes, rivers, marshes, and city ponds) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How mallards find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Mallard role in the food web
As consumers in their food web, mallards move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild mallards. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Appearance and the eclipse
The drake mallard is striking, with an iridescent green head, white neck ring, chestnut breast, and bright yellow bill, while the hen is mottled brown to stay hidden on the nest. Both show a blue-purple wing patch called a speculum. For a few weeks in summer the male molts into a dull, female-like "eclipse" plumage while he is briefly unable to fly.
Dabbling and diet
Mallards are dabbling ducks, tipping forward in the water with their tails in the air to reach plants and small animals below the surface rather than diving. They are omnivores, eating seeds, aquatic plants, insects, worms, and small invertebrates, and in parks they readily accept food from people, though bread is poor nutrition for them.
