The crag chilia is the sole member of the genus Chilia, a specialized earthcreeper adapted to life on steep rock faces. It spends much of its time clambering over boulders and cliff crevices in north-central Chile. Nests are typically tucked deep within rocky cracks, offering protection from predators and harsh weather. Its rufous tail with a darker tip is a key field mark when it darts between rocks.
Temperament
secretive and territorial
Flight Pattern
short rapid wingbeats with low, direct dashes between rocks
Social Behavior
Usually found singly or in pairs that maintain year-round territories on rocky slopes. Pairs nest in deep crevices or holes in cliffs and boulder piles, lining the cavity with grasses and fibers. Clutches are small, and both parents participate in incubation and feeding.
Migratory Pattern
Resident
Song Description
Song is a sharp series of metallic chips that accelerates into a trilled rattle, delivered from a prominent rock or ledge. Calls include dry clicks and chatters used to keep contact with a mate across broken terrain.
