## Abstract

We, the U.S. Fish and Wildlife Service, change the regulations governing control of introduced migratory birds. The muscovy duck (Cairina moschata) occurs naturally only in southern Texas. It has been introduced in other locations, where it is considered an invasive species that sometimes creates problems through competition with native species, damage to property, and transmission of disease. We amend the regulations to prohibit sale, transfer, or propagation of muscovy ducks for hunting and any other purpose other than food production, and to allow their removal in locations in which the species does not occur naturally in the contiguous United States, Alaska, and Hawaii, and in U.S. territories and possessions. This requires revision of regulations governing permit exceptions for captive-bred migratory waterfowl other than mallard ducks, and waterfowl sale and disposal permits, and the addition of an order to allow control of muscovy ducks, their nests, and eggs. We also have rewritten the affected regulations to make them easier to understand.
