An Australian Raven initially flew from the west bank of the Murrumbidgee across to the east bank, high in the sky and kept going towards the high ground. A little while later a raven, possibly the same one, came flying in the reverse direction before landing in the trees along the higher ground towards the west of the river. I could not see where it landed. In looking at the photographs there appeared to be an egg-shaped object in its beak.
