What the maximum lifespan of Superb Lyrebirds?

The correlation between weight and longevity in passerines would suggest
a maximum lifespan of tens of years.  They are largely ground dwellers
which I assume is associated with reduced longevity but this maybe
counterbalanced by the Tasmanian birds as an introduced species being
free of some factors which reduce longevity.
