It would be interesting to know if the lyrebirds that were introduced into
Tasmania from the mainland in the 1930s & '40s continued to mimic calls of
some mainland bird species that aren't present in Tasmania (if they did so
beforehand), or if they readily began to mimic local bird calls instead.
It would be even more interesting to know if any of the descendants of the
translocated lyrebirds mimic the calls of any mainland bird species that
their ancestors mimicked.
Such information would help us understand better the nurture vs nature
debate.

Hi Ralph,
I recorded several Superb Lyrebirds in the Hastings Caves region in 2006
including a male making chainsaw noises in between it's Black Cockatoo and
Rosella mimicry. I'd say well established at this point unless things have
changed in recently.
Regards,
Chris
