The rufous-tailed scrub robin is found flitting among dense cover but also in more open positions on trees, the tops of bushes and on posts. It is frequently seen on the ground hopping about and flaring and bobbing its tail up and down. When perched it also displays its tail in this way and also sometimes droops its wings before giving them a little flick forward. It feeds mainly on the ground on insects such as beetles, grasshoppers and the larvae of butterflies and moths, and on earthworms, turning over the
leaf litter to find its
prey. The male rufous-tailed scrub robin has an unusual display flight involving a downward swoop with uplifted wings and may sing while displaying. The nest is built a few feet off the ground in a bush, a hedge of
prickly pear, on a tree stump or other concealed place. It is usually well-hidden and is untidily built of grasses, stems, roots and other fibres. The inside is neatly cup-shaped and is lined with fine roots, hairs and often a piece of
snakeskin. A clutch of four to five (occasionally fewer) eggs is laid. The eggs average about and have a pale greenish or greyish-white background colour liberally sprinkled with greyish-brown spots. ==Ecology==
