The Australian name for Owl finches is Double bar finches.
You are so lucky to have them Aussie bird.
The only place I see them is in my Avairy, with the canaries, Zebs and King Quail.
We have regular visits from the Red Tailed Black Cockatoos. While a pair of blue tounge lizards are residents who expect their water bowl filled in the hot weather.
The resident Willie Wagtails like us to rake over the mulch so they can forage, while the Local Murder of Ravens make a huge mess of the bird bath, soaking all manner of things to soften. As it is cooling off the risk of visits from Gwardars has all but dried up for another season. The mice are starting to show up after a nice long break, so the Goshawks may turn up if the food supply elsewhere is not good. Lots of various size honeyeaters, quantities and types vary as the seasons do.
