For those of you that have never seen these birds, they are massive, with a wing span of 80 inches or 2 meters. The length is about 4 feet.
I think they are getting close to nesting time as there were quite a few squabbles going on.
Who started it is hard to say. One minute they are peaceful and the next the feathers are flying!
And flying
And flying
Nobody seemed to get hurt, although a few feathers were ruffled (pun intended).
