i have had a little bird come regularly into my house looking for spiders. He hops along the ground, is the size of a wren or thorn bill. Has a short tail, so not a wren. Is dark brown on upper side and a rusty brown underneath. Black eye, no eyebrow. Dark legs. No other markings I can see, only the dark brown and rusty colours. It has a sharp call. I've also seen it outside and behaviours in a similar manner to a robin, by siting on the fence and darting to the ground when it spies something to eat.
its not a dusky robin, I don't think, and it's seems to be the wrong colour for a female of any of the usual small birds I see in the Blue Mountains NSW. Help please.
