The upperparts are dark brown to slate-gray, with a rusty-tinged wing panel and reddish-brown underparts. The tail is long and graduated, while the wings are short and rounded.
It favors dense undergrowth in primary montane evergreen forest. It walks and hops along the ground while feeding on large insects, beetle larvae, and small snails.
