Pardon my ignorane but weren't Dingos introduced to
Australia? Does a period of thousands of years matter
in relation to an introduced species?

Dingos were introduced and were probably responsible for the extinction of some of the larger species soon after their introduction. Since then they have settled into an equilibrium with the remaining species, and as Laurie Knight indicated, recently become a major predator of cats and foxes. As Chris Johnson (/Australia's Mammal Extinctions A 50,000 Year History/) suggests, there have been fewer recent extinctions of animal species the range of which coincides with that of the dingo. So much so that there have been calls to allow dingos to extend their range back in towards settled areas as a way of controlling the more recent predators, cats and foxes.

In a thousand
years time will cats and foxes be protected?
Yes, again;  if humanity keeps up its stupidity.

In a few thousands of years we might consider cats and foxes as protected, since they could well be instrumental in keeping yet other, new, feral species at bay which prey on the few remaining species still extant, but keeping in mind that at the same time they were responsible for the extinction of half of the small mammals that lived in the 21st century.



Now back to birds.....if your driving up, Port
Macquarie is a good spot for Barred Cuckoo-shrike
especially if the figs are fruiting. Try the loop walk
through Kooloonbung Creek NR.
