It's funny you mention psittacines, because we have
many of psittacine where I live...they are easily the most plentiful birds in this region. My local species are:
Yellow-tailed black cockatoo
Sulphur-crested cockatoo
Little corella
Galah
Rainbow lorikeet
Musk lorikeet
Purple-crowned lorikeet
Adelaide rosella (and occasionally Eastern rosella)...grrr they eat all my plums and apricots!
Red-rumpled parrot
Occasional Elegant parrot, Blue-winged parrot and Budgerigar sightings
Phew! As you can imagine they make quite a noise!
Especially those sulphur-cresteds... We're towards the end of the breeding season at last... with the fledgling galahs and cockies it can get pretty cacophonous at dawn and especially dusk. The fledgling galahs make an awful screeching/choking noise when they are being fed... Exactly like you would if you were trying to screech while your mother jammed her face into yours to spit food down your throat, haha. And the fledgling sulphur-cresteds sound like a deranged version of their parents...hard to describe but it's a bit like a screeched sneeze, if that is at all possible.
As for Corvids... The only species we have here where I live, as far as I know, is the Little Raven,
Corvus mellori. Of course many people mistakenly think the Australian magpie (
Gymnorhina tibicen, syn. Cracticus tibicen) is a corvid but it a member of the Artamidae family, with currawongs and butcherbirds and woodswallows... Common names are problematic, huh! I think it's understandable that people confuse Australian magpies with corvids because our "maggies" are pretty intelligent, too, and live in complex family groups.
The other plentiful bird group here is Meliphagidae, the nectivores/honeyeaters. There are many, many, many. Slightly less visible than the parrots, as they are smaller and a bit quieter.
The tiny finches, thornbills, etc., are the hardest to spot but I think they offer the greatest reward.
I just wish I could photograph the ones that visit my garden...
ETA: oops sorry, yes, I live in South Australia, in a rural town in the Mount Lofty Ranges.
