More information -
This is a group of kookaburras I often see - I took the photograph from my 
balcony, and they were not far away. There was a group of four and the ‘battle’ 
lasted around 5 minutes.  I saw the beak hanging behaviour twice. Afterwards 
they all flew off together. I did wonder if there were juveniles involved.

This is another photo of the two involved.
