      Whenever, after investigation, the Secretary of the Interior
    shall determine that it is compatible with the preservation of the
    bald eagle or the golden eagle to permit the taking, possession,
    and transportation of specimens thereof for the scientific or
    exhibition purposes of public museums, scientific societies, and
    zoological parks, or for the religious purposes of Indian tribes,
    or that it is necessary to permit the taking of such eagles for the
    protection of wildlife or of agricultural or other interests in any
    particular locality, he may authorize the taking of such eagles
    pursuant to regulations which he is hereby authorized to prescribe:
    Provided, That on request of the Governor of any State, the
    Secretary of the Interior shall authorize the taking of golden
    eagles for the purpose of seasonally protecting domesticated flocks
    and herds in such State, in accordance with regulations established
    under the provisions of this section, in such part or parts of such
    State and for such periods as the Secretary determines to be
    necessary to protect such interests: Provided further, That bald
    eagles may not be taken for any purpose unless, prior to such
    taking, a permit to do so is procured from the Secretary of the
    Interior: Provided further, That the Secretary of the Interior,
    pursuant to such regulations as he may prescribe, may permit the
    taking, possession, and transportation of golden eagles for the
    purposes of falconry, except that only golden eagles which would be
    taken because of depredations on livestock or wildlife may be taken
    for purposes of falconry: Provided further, That the Secretary of
    the Interior, pursuant to such regulations as he may prescribe, may
    permit the taking of golden eagle nests which interfere with
    resource development or recovery operations.
