RUNNER-UP, ANIMAL BEHAVIOUR
Western grey kangaroos
The light was low in the wandoo bushland where I watched these young western grey kangaroos (Macropus fuliginosus). At this age, they often engage in play fighting where they throw their heads back, put their arms up and occasionally even kick. In between, they stop to have a scratch before starting again.
