This video is called Australasian Bittern.
From Birdline Victoria in Australia:
Tuesday 30 June
Western Treatment Plant (Werribee)–Western Lagoons
Thanks to Paul Newman who spotted the bird, the bird spent most of the time in the drain on the left hand side as you enter Western Lagoons via Gate 2. It did, however, move around the centre ponds as well. Time was about 4pm.
