Noisy miner
They are sometimes called native miners, native mynas or native mynahs (actually an Indian spelling), and, in older bird books they might have up to twelve different names.  At one time they were thought to be mainly bee-eaters, but they eat the nectar of Australian native flowers. They are also known to eat fruit and insects, and at times small reptiles and amphibians. While the name is often spelled myna, or mynah, they are not related to the introduced brown/black-feathered "Indian" or "Common mynah" which is usually slightly larger and often found in the same area.
