Mallards are a common species of duck found in many parts of the world. They are easily recognizable by their vibrant green heads, yellow bills, and distinctive white neck rings in males. Females are mottled brown and have an orange bill, which helps them blend into their surroundings. Mallards are often seen in wetlands, lakes, and rivers, where they feed on aquatic plants, insects, and small fish. These ducks are known for their adaptability and can thrive in both urban and rural environments. Mallards are also migratory birds, traveling long distances between their breeding and wintering grounds. They typically nest on the ground near water and are known for their strong parental care, with females leading their ducklings to water shortly after hatching.
