Cindy said these are Honeyeaters, though my rapid googling did not find any that looked exactly like them. But they’re pretty funny, perching on lines and flapping up and down just outside of windows. I think they’re also the ones we’ve seen attacking corellas and some birds of prey up above the bush.
This one might be a butcherbird, though the beak seems too small, or a magpie, though the pattern seems odd.
Birds are neat.
