50 CFR § 21.54 - Control order for muscovy ducks in the United States.
(a) Control of muscovy ducks. Anywhere in the contiguous United States except in Hidalgo, Starr, and Zapata Counties in Texas, and in Alaska, Hawaii, and U.S. territories and possessions, landowners and Federal, State, Tribal, and local wildlife management agencies, and their tenants, employees, or agents may, without a Federal permit, remove or destroy muscovy ducks (Cairina moschata) (including hybrids of muscovy ducks), or their nests, or eggs at any time when found. Any authorized person may temporarily possess, transport, and dispose of muscovy ducks taken under this order.
(b) Muscovy ducks in Hidalgo, Starr, and Zapata Counties in Texas. In these counties, take of muscovy ducks, their nests, and their eggs may be allowed if we issue a depredation permit for the activity.
(c) Disposal of muscovy ducks. You may donate muscovy ducks taken under this order to public museums or public institutions for scientific or educational purposes, or you may dispose of them by burying or incinerating them. You may not retain for personal use or consumption, offer for sale, or sell a muscovy duck removed under authority of this section, nor may you release it in any other location.
(d) Other provisions.
(1) You must comply with any State, territorial, or Tribal laws or regulations governing the removal or destruction of muscovy ducks or their nests or eggs.
(2) You may not remove or destroy muscovy ducks or their nests or eggs if doing so will adversely affect other migratory birds or species designated as endangered or threatened under the authority of the Endangered Species Act. If you use a firearm to kill muscovy ducks under the provisions of this section, you must use nontoxic shot or nontoxic bullets to do so.
(3) If you operate under this order, you must immediately report the take of any species protected under the Endangered Species Act, or any other bird species protected under the Migratory Bird Treaty Act, to the Fish and Wildlife Service Ecological Services Office for the State or location in which the take occurred.
(4) We reserve the right to suspend or revoke the authority of any agency or individual to undertake muscovy duck control if we find that the agency or individual has undertaken actions that may harm Federally listed threatened or endangered species or are contrary to the provisions of this part.
