I agree with your first point and have already written on that. The second
point is quite interesting too I'll have to check up on what those nine are,
I suspect it is an underestimate. Chisholm, years ago compiled I think a
longer list of "mimics".  I think it is relevant that Brown Thornbills are
often reported to indulge in bouts of vocal mimicry whilst being handled for
banding. I have previously requested info on this before on this line but
haven't done anything with it.
