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.
