Wild Eurasian Blackbird (Turdus merula)

I didn't know this species was introduced in Australia.

@Great Argus It’s very common to abundant in south-eastern Australia, especially around parks and gardens.
Some other introduced bird species including Song Thrush, European Greenfinch, European Goldfinch, Tree Sparrow and Eurasian Skylark.
There are many others (ie. starlings, four pigeon species etc) in Australia.
