An introduced species should not be of such concern as native species.  However, it would merit thought if the decline of the introduced species is an early warning of decline in the indigenous species (for example a worsening drought kills off the species that are not as well adapted to drought before the natives start to die). 

My understanding is that the Bassian Thrush was much more common in what is now the urban part of the ACT before Common Blackbirds arrived. and that they did compete for resources.

All very interesting observations but they are an introduced species so I am not concerned about their decline. Besides, they are all at my place, 4 this morning bouncing around the back yard. Then chasing each other and making a racket. Are they competition for the Bassian Thrush?
