Detailed introduction
The Silver Teal (scientific name: Anas versicolor) has three subspecies. It is a medium-sized waterfowl belonging to the genus Anas in the family Anatidae.
Silver ducks primarily float on the water's surface, foraging underwater. Their diet consists mainly of plants, but they sometimes consume animal matter. They have webbed toes but rarely dive, swimming with their tails above the water. They are adept at foraging, playing, and courting in the water. They are clean animals, frequently preening their feathers both in the water and on land. Their diet consists mainly of roots, seeds, leaves, cardamom, and rice from marshes and lakes, but they also eat invertebrates and arthropods.
The breeding season for silver ducks is from October to February. They build a bowl-shaped nest using plant stems, placing it above the nearby water and concealing it among aquatic plants. Each nest contains 4 to 12 eggs, which incubate for 30 days. The chicks leave the nest at 60 days old and are usually incubated solely by the female duck. After hatching, the female continues to care for the chicks, who follow her to forage.
