Nothing its just the same as asking whats the difference between a dog and a shiba inu. It is just a type of duck which in turn is a type of waterfowl which is a type of bird. Others are muscovy etc. hope this helps
Mallard ducks were never introduced. Mallards were the first duck ever on planet Earth.
No.
The population of mallard ducks in Louisiana is estimated to be around 1.2 million.
The Mallard duck is the ancestral precursor to all domestic ducks except Muscovy ducks. The white ("Long Island duckling"), type of farm pond duck descended from and can still interbreed with mallard ducks. Although the domestic ducks are usually significantly larger, feral ducks often revert to mallard characteristics after a few generations. The mallard is the essential "type O" duck that dominates the duck gene pool. They're native only to the Americas but because of introduction they have been established on every continent except Antarctica. Mexican Ducks and Hawaiian Ducks are also mallard hybrids, and ornithological scientists now generally agree that all Black Ducks in existence are now carrying mallard DNA. They hang out with the white ducks, and vice versa, because they're "cousins" and share the same habits and characteristics in feeding, breeding, and nesting.
Same as the male, orange.
Mallard ducks are not capable of changing gender. There is no known species of duck that is capable of that.
Nope, all ducks, geese, chickens, guineas and soforth are birds. Mammals have fur, usually, and don't lay eggs. (The Platypus and Echidna are one exception.)
