Muscovy Ducks are native to Mexico, Central and South America. A small number of truly wild Muscovy Ducks can be found in the Rio Grande Valley in Texas. The wild ducks are iridescent black with white wing patches. The Lake Ella ducks are quite varied in appearance but, of all the ducks we saw, this one looks most like the wild ducks. However, a wild Muscovy would have black legs and feet, not yellow.
