Whilst I agree with most of your comments about the sprawl in the western
plains of Melbourne, I think this has little to do with Song Thrush decline.
They are a bird of established gardens and woodlands and most of the area
being destroyed is grassland. Indeed - with a lot od new gardens there may
end being more Song Thrush territory in years to come! The Thrush has
declined in developed areas throughout Melbourne (I live in Werribee in an
established area and they have declined a lot - they also used to be in the
wooded areas of the Western Treatment Plant but are now scarce). Drought
seems the answer - my wife is a keen gardener and is no longer troubled by
snails so the connection seems obvious (but of course may not be!)
