@UngulateNerd92 sorry, I didn't take a photo of the signs and the signage is way to blurry to read on the image, although it might be possible for someone more knowledgeable on birds than myself to identify them
I will say, of the species in this display case, off the top of my head, I can identify some of them but not all of them.
Out of the ones I can identify, there's Budgerigar, Rainbow Lorikeet, Eastern Rosella, Cockatiel, Sulphur-Crested Cockatoo, Galah, Major Mitchell's Cockatoo(not 100% sure on that one), Little Corella and Yellow-Tailed Black Cockatoo
Also: Crimson Rosella, Pale-headed Rosella, Varied Lorikeet, Scaly-breasted Lorikeet, Musk Lorikeet, Eclectus Parrot, Red-winged Parrot, Australian King Parrot, Australian Ringneck, Mulga Parrot (+ a couple more)
