In the canopies of the Australian eucalyptus forest, a Noisy Friarbird parent defends its territory against another intruding Friarbird. As echoed squawks surround the area and feather ruffle, the branch shakes with each move taken. Resiliently, the parent pushes the intruder off the twig while shouting once more. Understanding utter defeat, the intruder reluctantly leaves the tree as it lets out a last squeal of fear and surrender.
