Yes, Stephen. I thought it was well known that the Tasmanian Superbs
continued to use mimicry of Whipbirds and Pilot-birds, neither of which
species occurs in Tassie. And these sounds were passed down through the
generations. But I've heard that in the absence of models the sounds have
now deteriorated beyond recognition. Not surprising after 60 plus years.
