So teeny-weeny!

I found this feather on the edge of the bird bath outside this morning and, after going right through my identify-a-bird book, can say with some confidence that this tiny feather comes from a tiny bird.
:)
Can't find them in the book, damn it. These birds splash around in the water a lot, and they're very cute, they're very little, they're kind of brownish and have some red on the back of their necks, or on top of their heads, or maybe it's under their throats? There's a bit of red on them somewhere, of this I'm almost sure. I'll try the book again next time there's a real bird out the window to refer to. It would be nice to know what they're called.

UPDATE

Red-browed Firetail (Neochmia temporalis)
