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!
Nobody seemed to get hurt, although a few feathers were ruffled (pun intended).
