Javan or Jungle myna? Kuala Lumpur, Malaysia (1 Viewer)

[AntarcticanShrike]

I spotted this individual @ KL, MY

I'm at my wit's end trying to identify him. I can't tell if he's Javan or Jungle. I'm colorblind AND the picture is not color-accurate so I'm not sure if there are blue-ish marks at the bottom of his bill (which would suggest that he is in fact a Jungle myna). I don't know any other way to tell both mynas apart.



Also, how would you differentiate and identify Javan, Jungle, and Crested mynas?

It's a Javan Myna.

Jungle Myna has a dark bill base while Crested has a paler, horn coloured bill, brighter orange-yellow eyes and plumage is all black, the under tail coverts with white tips.
