Song Thrush is only 85% of the size of the Bassian. ( 23cm as opposed to
26-27cm)
The Bassian is a bigger, much plumper looking bird with much more
white around the eye, and its breast and belly has horizontal crescents
( ends upwards) of dark brown rather than the vertical streaks/spots on
the Song Thrush.

Bassian Thrushes occasionally turns up in Melbourne parks along the
Yarra. I've seen them at Banyule and in Ivanhoe, and i am prepared to
believe that they are possible at the Botanic Gardens. Song Thrush are
now quite rare after the long drought.
Song Thrush is almost the same size as Blackbird - maybe slightly
shorter - and very similar in general look. but it has much lighter
coloured bacl and heqd plumage. It matches the colour of dry ground,
while imature or female blackbird matches the colour of wet ground.
Song Thrush is seldom seen out in the open, usually under shrubs and
bushes except in dark cloudy conditions or twilight. Cream underneath
with dark streaks. Rather rufous underwing may be seen in flight.
Bassian Thrush likes shrubbery too but is quite a bit larger than
Blackbird or Song Thrush. Tends to hold its head more in line with its
back than the others. All feathers have a bold, scaly dark edge on
both brown back and white underparts.
Slater's first edition left Blackbird out altogether and now squeezes it
in at the bottom of a page - makes it hard to compare Zoothera and
Turdus thrushes.
