Mimicry by Magpie

Hi Syd,

Years ago I was camped in the Border Ranges National Park, when it was known 
as Wiangaree State Forest, and I awoke to the sound of tapping.  It was an 
Albert's Lyrebird bashing a large rainforest Snail (Hedleyella falconeri) on 
the buttress of an ancient Antarctic Beech tree at the foot of my tent.
Later on I heard a male Lyrebird calling and its repertoire included mimicry 
of a number of rainforest birds.  Amongst the calls was an unusual sound 
which, at the time I thought was either the sound of a car braking suddenly 
on the gravel road or gushing water.  I wasn't that familiar with many bird 
calls in those days so I suppose that the call could have been that of a 
Paradise Riflebird or possibly a Masked Owl but I still favour the skidding 
car explanation.
Have you heard any Albert's Lyrebirds mimicking a noise that fits this 
description?
