Small, crepuscular, stocky heron with short legs. Adults unmistakable with black cap, black back, grey wings and white underparts. Immature less distinct, and may be confused with immature Squacco Heron, Little Bittern or Bittern. Differs from all these in distinct white spots covering both wings and back. Belly and breast are more widely covered in coarse streaking, not just the sides or upper chest. Legs just barely protrudes behind tail in flight.
Sound:Most commonly hear call is a nasal, soft croaking "roack", like cross between Raven and frog.
