Hi Chris,
The danger of making claims (both on the evils of the Common Mynah, and like
yours, against those claims) is that they are mostly based on anecdotal
evidence. Without saying that they are definitely bad or definitely not a
threat, I can offer an easy counter-example to your observations - I watched
a group of Common Mynahs defend the best tree hollow in my local park
against all comers. They actually turfed a pair of Galahs out of the hollow
that had already begun to nest, and then successfully kept Rainbow Lorikeets
and Pale-headed Rosellas out of the hollow for the rest of the season. I
have a flock of 100 Common Mynahs living in my local area and while I have a
good diversity of birds in that park, I am sure that this vigorous
interference in the breeding activities of the natives must have some
impact, particularly when hollows are such a scarce resource.
Regards,
Chris
