Ecological Notes: 

The species can be observed around freshwater rivers, lakes, bulrushes, estuaries, harbours and in residential fishponds hunting for goldfish. Whilst its common name would indicate that it is a nocturnal hunter it is not strictly nocturnal, often feeding during the day.

Additional Notes: 

The species is a solitary hunter, but also can be  gregarious, forming small colonies especially if food is scarce.
