I'll throw another anecdote on the fire, but it's a fairly large
sample size anecdote so it may be useful.
I've spent a bit of time in the wilderness, climbing and scroggin
munching (bushwalking), and have never seen a Mynah away from the
fringe areas. Nor in manyof the rural/national park fringes, such as
the Capertee, or somewhere I've spent more time, the Wolgan Valley,
just south of Capertee. Definitely a bird of the flat/open grounds
with open canopy and preferably urban disturbance. Locally they almost
exclusively use non-native trees. In particular a dense conifer on my
street and the horrific palm trees in Blaxland on the highway.
