Limitations

  • Protected status under Migratory Bird Treaty Act
  • f 1918 prevents nest destruction when eggs of

laying has commenced by any of those birds, all nest destruction must cease. Destruction of empty nests in an active or partially active colony will likely threaten surrounding nests that contain eggs or nestlings; therefore it will not be allowed except

determined by the Migratory Bird Permits Office.”
