I still remember the playground cry of "Fight, fight, fight............" as two protagonists sorted out some problem that could only be resolved by a punch up. Today a couple of noisy magpies alerted me to the garden version today.
While two or perhaps more Magpies noisily shouted from a tree, two others were locked in battle on the ground.
At first it looked like a bundle of feathers on the ground, but then they sprung to life and preceded to grapple in an intense fight.
Eventually one seemed to have the upper-hand and pinned the other bird to the ground, with a claw on its throat.
Such was the ferocity of the attack I fully expected that the dominant bird would end up killing or maiming its adversary.
In the end the grounded bird managed to break away and get to its feet, but not before it took a few blows.
