Whenever any person has been given written permission by a state or federal
agency, with the proper authority, to kill birds which are damaging private
property, the Chief of Police shall, upon presentation of such written permit,
grant authority to the person named in a written permit to kill birds within the
corporate limits of the City. No permit shall be issued by the Chief of
Police to any person to kill birds which are damaging private property within
the City, unless such person has first been given a written permit by a duly
authorized state or federal agency.
