Muscovy ducks are unusual Florida residents. They hiss instead of quack, they fly clumsily, and they somehow flourish in Florida’s urban environment. Native to Central and South America, they have lived in Florida for many years and can be found near lakes and canals statewide.  These birds were illegally released primarily by private individuals for ornamental purposes or as pets. Muscovy ducks can be extremely prolific and local populations can increase dramatically in a short time. As a result, controversies frequently arise between residents who enjoy the birds and residents who consider them a nuisance. When you have a large number of ducklings multiple times a year, a duck mother is kept busy herding.
