Hi Carl , Kingfishers do indeed fight and it can be a very violent encounter, I watched a pair battle for an Hour the birds taking a rest from time to time then resuming the battle, on several occasions the birds locked beaks one attempting to drown the other ,it was quite a spectacular fight. If you copy and past these links you can see some pictures of this contest.
