duck mulard duck WIKIPEDIA:Mulard_duck The Mulard (or Moulard) is a hybrid variety of domestic duck produced by crossing a female Pekin with a male Muscovy Duck. Since the domestic Pekin is descended from the Mallard Duck (*Anas platyrhynchos*) and the Muscovy (*Cairina moschata*) is a separate species, all Mulards are sterile F1 hybrids. Most are bred through artificial insemination, and are sometimes also called "mule ducks". mule duck requires discussion
