The Eagle is being approached by an adult Eagle likely one of its parents. They don't share food at this point in their relationship the adult is coming in to take the fish or what is left of it.
He was working his way aaround the estuary staying clear of Georgina. Two years later he would challenge her for the dominance at the fishing hole.
At this point she has a good 6 fish...actually 5 the immature Eagle ate one.
