(a) In general. The regulations in this part apply to all eligible persons harvesting migratory birds and their eggs for subsistence purposes in Alaska between the dates of March 10 and September 1. The provisions in this part do not replace or alter the regulations set forth in part 20 of this chapter, which relate to the hunting of migratory game birds and crows during the regular open season from September 1 through March 10. The provisions set forth in this part implement the exception to the closed season, which authorizes the taking of migratory birds in Alaska for subsistence purposes between March 10 and September 1.

(b) Land ownership. This part does not alter the legal authorities of Federal and State land managing agencies or the legal rights of private land owners to close their respective lands to the taking of migratory birds.

(c) Federal public lands. The provisions of this part are in addition to, and do not supersede, any other provision of law or regulation pertaining to national wildlife refuges or other federally managed lands.

(d) Migratory bird permits. The provisions of this part do not alter the terms of any permit or other authorization issued pursuant to part 21 of this chapter.

(e) State laws for the protection of migratory birds. No statute or regulation of the State of Alaska relieves a person from the restrictions, conditions, and requirements contained in this part. Nothing in this part, however, prevents the State of Alaska from making and enforcing laws or regulations that are consistent with the regulations in this part, the conventions between the United States and any foreign country for the protection of migratory birds, and the Migratory Bird Treaty Act, and that give further protection to migratory birds.
