is this the same species?

I found this bird around the Cinnamon Bittern that day, is this a juvenile or is it only a Chinese Pond Heron?

This one looks like a Yellow Bittern.

Yes! You can find different from their eyes.^^

Interesting observation.

Several Bittern species have a dark mark at the rear of the iris - Schrencks's and also Cinnamon it appears.
Here is an old Screnck's photo of mine



but it seems Yellow Bittern does not.

I still don't know what the function of this dark iris mark is.
