that the small population which made up the ancestors of Australian
Blackbirds was not representative of the general population in Britain
at the time, and included many poor singers, therefore the average
quality of song has declined in Australia.
It (the suggested poor singing ability) certainly hasn't lessened their
"fitness" in a general sense - they now occupy very diverse habitat and
climatic zones in Australia, and are still steadily spreading into
semi-arid and subtropical bits of Australia in addition to the more
predictable temperate bits. A very successful feral.
