“In the field it is not that easy to differentiate the Javan Myna (Acridotheres javanicus) from Jungle Myna (Acridotheres fuscus).
“The key features quoted in literature include:
1. Location – this is useful but with the spread of the Javan Myna we need to be more careful.
2. Javan plumage is more ‘slaty-grey’ compared to the ‘browner’ Jungle Myna. But lighting can easily affect an appreciation of this subtle difference.
3. Possibly the best feature is the bluish colour of the base of the Jungle Myna bills (dark looking in the field). Even this can be hard at times.
4. Two composites of different birds – Javan on the left.”
