I floated this idea once before - maybe 3-4 years ago - and got little
response at the time.

I've seen a little bit of circumstancial evidence to suggest some
migration by Common Blackbirds in southern Victoria.  At a couple of
places in autumn, a copse of trees in a rural landscape, a number
(5-10) blackbirds flushed noisily out of them when I stepped in -
behaving like a small fall of migrants rather than local birds - not
the kinds of sites routinely occupied by blackbirds & at greater
density than expected.  I admit the details are scanty and open to a
number of interpretations, but I think it's worth keeping an eye out
for this kind of thing, to see how widely it occurs.

It suggests to me also that they will eventually colonise a much
larger area of Australia than they currently occupy, as they have
potentially great dispersive ability over otherwise hostile terrain.
