I can't be sure this one is Yellow Bittern or Cinnamon Bittern Juvenile. Can't tell the difference. Not sure if the "black spot" behind the iris can be use as indication it is Cinnamon Bittern? And the plumage pattern suggested is Cinnamon Bittern Juvenile/Immature?

All photos below are same bird. It is unfortunate no shot of the legs. Thanks.

Immature Cinnamon Bittern IMO - it doesn't look like Yellow and lacks the white spots on the upper parts of von Schrenks's.

Thank you for confirming @andyb39. Appreciated.

Also 'C' shape in the eye also is a pointer I suppose.

Thank you @Vyomkesh . So that is called 'C' shape instead. I did noticed a black spot behind the iris, just not sure if that can be use as one of the key identification.

The black marks behind the iris (creating the yellow C at the front) are a feature of both Cinnamon and von Schrenck's Bittern, but not found in Yellow Bittern
