(1) Removal of the hind toe from the right foot.
(2) Pinioning of a wing: Provided, That this method shall be the removal of the metacarpal bones of one wing or a portion of the metacarpal bones which renders the bird permanently incapable of flight.
(3) Banding of one metatarsus with a seamless metal band.
(4) Tattooing of a readily discernible number or letter or combination thereof on the web of one foot.

(d) When so marked, such live birds may be killed, in any number, at any time or place, by any means except shooting. Such birds may be killed by shooting only in accordance with all applicable hunting regulations governing the taking of mallard ducks from the wild: Provided, That such birds may be killed by shooting, in any number, at any time, within the confines of any premises operated as a shooting preserve under State license, permit, or authorization; or they may be shot, in any number, at any time or place, by any person for bona fide dog training or field trial purposes: Provided further, That the provisions:
(1) The hunting regulations (part 20 of this subchapter), with the exception of § 20.108 (Nontoxic shot zones), and
(2) The Migratory Bird Hunting Stamp Act (duck stamp requirement) shall not apply to shooting preserve operations as provided for in this paragraph, or to bona fide dog training or field trial operations.

When properly marked, such carcasses may be disposed of to, or acquired from, any person and possessed and transported in any number at any time or place.
