Hi Geoffrey, Julian and others.
I have heard or read that Galah chewing of bark actually helps fungi and insects to invade the wood of Eucalypts, thus leading, in the long term, to the creation of new hollows.
I cannot provide scientific evidence of this, but it does appear to make sense to me.
I cannot credit the Galahs (and other Cockatoos) with the foresight to plan for that outcome, but on an instinctive level, such behaviour could well advantage those species (and fellow hollow-dwelling creatures).
