Red Winged Black Bird v. White Egret

​An egret appeared next to the west shore of the large pond.  It was constantly harassed by a herd of red-winged blackbirds.  I was wondering if the black birds acted out of being territorial, like what the blue jays did to the owl a while ago.  Finally the egret opened his mouth and screamed: "Enough is enough!".  He was then left alone to move on.  I gave the egret a thumbs up.
