Quick answer
Mallards feed on plants, seeds, invertebrates, and grain, adjusting with season, age, and what is abundant in Ponds, rivers, marshes, and parks worldwide. 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, invertebrates, and grain. Anatomy and habitat (Ponds, rivers, marshes, and parks worldwide) 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.
Distribution and habitat
Mallards live in Mallard native across Eurasia and North America; introduced to Australia, New Zealand, South Africa, and South America. Preferred habitat includes ponds, rivers, marshes, and parks worldwide. Across Africa, Asia, Europe, North America, Oceania, South America, population density reflects prey availability, water access, and human disturbance. Protected areas and wildlife corridors remain essential for
Physical traits and behaviour
Mallards typically reach about 0.6 m in length and 1.2 kg in weight, with top speeds near 80 km/h. The familiar puddle duck. Daily activity, social structure, and seasonal movements reflect pressures in their native environment.
