Habitat
The Rock Wren is found in arid or semi-arid habitat, in shrubby areas in rocky canyons and cliffs, on rock slides and boulder-strewn slopes, and in arroyos with sparse vegetation. Sometimes seen around concrete and stone buildings. Similar to Canyon Wren in habitat, but in Idaho, Rock Wrens are more widely distributed. The Rock Wren nests in cavity or crevice, under or near rocks. Forages on ground, or takes food from foliage. Few studies have been conducted on this species.

Diet
The Rock Wren feeds on insects and spiders, as well as earthworms and larval insects.

Reproduction
The female Rock Wren incubates 4-10 eggs (usually 5-6) in northern range, fewer in south. Young are tended by both parents.
