Well it may SEEM so to John but the data
indicates otherwise. The species is the 15th most often recorded species (based
on 17 years of COG's GBS) and the 6th most often recorded breeding species
comprising 2.268% of the total bird fauna of Canberra. It is also the 6th most
often recorded breeding species. Its numbers increased steadily over the first
ten years of the GBS and for the last seven years its abundance has steadily
declined (though still above the levels of 1981. This is hardly an insignificant
species. As others have said, it infiltrates quite extensively into surrounding
bushland.

blackbirds
I'm surprised by how little Blackbirds seem
to impinge on native birds in
Canberra, they don't seem very numerous or
visible at all. On the other
hand I am impressed by the way that they
have spread to places like
Robinvale on the Murray (so unlike northern
Europe).
What does surprise me is that they haven't discovered Wet
Forest by now
(the habitat closest to their original one in Europe); if
they had I'm sure
they'd have been through it like the proverbial dose
of salts, in the
process displacing various ground
feeders.
However it doesn't appear that they have, so let's hope
there's something
wrong with se Australian Wet Forest, from a Blackbird
point-of-view (not
enough worms, not the right sort of worms, or
whatever) and that Australian
Wet Forests stay Blackbird free (unlike NZ
forests, and the bush on Lord
Howe Island).
