Can mallard duck fly?

Although mallard is a distant relative of domestic ducks, mallard can fly, and its body length is similar, but its weight is much lighter than that of domestic ducks, generally only about one kilogram, because the task of domestic ducks is to eat and sleep, with the aim of gaining meat. However, mallard ducks need a lot of energy to fly at high speed, which is lighter than domestic ducks, normal and convenient for long-term flight. Flying birds generally do not condescend to the natural environment, especially climate change. When it's cold, I fly to the south, and when it's hot, I go to the north. In any case, many birds have special protein in their eyes, which can sense the strength of magnetic field lines, so flying mallard ducks are no exception. Every March, they began to migrate to the south in groups, and from September to June, they migrated to the north in batches at 5438+00.
