When it’s not just Jousting


 
You're not biting me
In the photo above, Boss Burra evades almost certain attack from his “Problem Child”. That's Bully Baby on the right, crouched & ready to strike.
 On occasions, my Kookaburra family will sit in the back trees and there will be squabbles.
These are displayed as “beak jousting”. They grab each other’s beaks and each tries to pry the other off its perch.

I think this a hierarchy thing. It never seems to get too aggressive & only last a few seconds.
And then there is Bully Baby Burra:
Didn’t he show his form from an early age!
While still a fledgling he would pick on his sibling (Brave Baby Burra), to the extent of forgoing food in preference to giving him a hard time. At the time I put that down to a nest thing. Multiple chicks in the nest vying for food & their parents’ attention.
But his aggression soon spread to the others. It didn’t matter the rank or relationship. There was no quarter given to anyone. They all copped it (and still do).
I mentioned this to my local vet, and due to Bully’s age, he didn’t believe it to be a territorial behaviour. He thinks Bully Baby is just a problem child.
The social relationships that have resulted due to this are interesting. When he flies up and lands next one of the family, they usually jump to another branch or tree (lest they get bitten).
 
All but Bitey Burra. Bully Baby seems to have forged some sort of relationship with his older brother.
They often sit side by side. This doesn’t make Bitey immune from attack, he cops it, but only a fraction of the time.
This was one of those times.
 
surprise, surprise
