Muscovy ducks are native to the tropical climates found in Central and South America, Mexico, and parts of Southern Texas. Since their introduction to the United States, they have also built up a presence in Florida and parts of New York, Washington, and California. They congregate in urban parks, especially those with bodies of water. Other favored habitats include forest streams, wetlands, swamps, mangroves, and freshwater ponds. In their native environments, Muscovies nest in tree cavities. The feral, non-native Muscovy ducks in the United States, however, tend to dig out shallow nests in the ground.
