Mallard vs. Teal — What's the Difference?

Mallards are a common species of wild duck known for their distinctive green heads in males and mottled brown plumage in females. They are larger ducks, typically found in a wide range of habitats including ponds, lakes, and rivers across North America, Europe, and Asia. Mallards are dabbling ducks, feeding on the water's surface or tipping forward to reach underwater plants and animals. Their flight is powerful and direct, with noticeable wingbeats.

Teals belong to a smaller group of ducks, characterized by their small size and swift flight. Males often display strikingly colorful wing patterns, especially noticeable during flight. Teals are found in a variety of habitats, including marshes and shallow ponds, and they have a more global distribution, including areas in Europe, Asia, Africa, and the Americas. Like mallards, teals are also dabbling ducks but they tend to forage in shallower waters. Their flight is rapid and agile, often executed in tight flocks, which contrasts with the more solitary or pair-based flight of mallards.

In terms of behavior, mallards are adaptable and can often be found in urban and suburban areas, becoming accustomed to human presence. They have a varied diet, eating plants, seeds, insects, and small fish. Teals, while also adaptable, are more often found in wilder, less disturbed habitats. They have similar diets but due to their smaller size, they may focus more on smaller prey and seeds.

Breeding differences are also notable. Mallards are known for their elaborate mating displays and are often monogamous for a breeding season. Teals, though also forming breeding pairs, have less conspicuous courtship behaviors and tend to nest in more concealed locations.

The conservation status of mallards is generally of less concern due to their wide distribution and adaptability. However, some teal species, due to specific habitat requirements, may face threats from habitat destruction and are closely monitored by conservationists.
