Aggressive Red Wattlebirds
This morning I was suddenly aware of a noisy disturbance just outside my office window. I looked up to see three Red Wattlebirds locked in a furious battle in the garden bed. In fact, I thought at first it was only two fighting each other. As I reached for my camera, they flew off, and I saw that there had been three birds fighting.
What caused this kerfuffle? I have no idea. As they flew off two of them were aggressively chasing the third one. The battle may well have continued elsewhere.
