I don't know, but I have always assumed that birds that perch this way (and
other robins do it too) may be surveying for a different range of insects
from those that perch upright on branches - particularly for insects of
lower strata and trunks.  The extreme of this behaviour may be the
"flushing" actions of Pied Monarchs.

Surely the Variegated Wren (in its many forms) is the most widespread
geographically - but as the Superb is the species of areas like Sydney and
Melbourne it may be the one seen by the most people.

There are a number of papers on the behaviour of other fairy wrens by such
authors as Ian Rowley and Robert Payne; look in recent issues of THE EMU,
including the guide to literature supplement published jointly with the
American and British Ornithologists' Unions.
