The rockrunner, also known as the Damara rock-jumper, is a species of African warbler, formerly placed in the family Sylviidae. It is the only member of the monotypic genus Achaetops. It is found in Angola and Namibia.
Region
Southwestern Africa
Typical Environment
Occurs mainly in rocky hills, inselbergs, and boulder-strewn slopes within arid and semi-arid savanna. It favors granite and sandstone outcrops with sparse shrubs and grasses, and uses crevices and ledges for cover. The species is locally common in suitable habitat in central and northwestern Namibia and extends into southwestern Angola. It is a year-round resident and typically remains close to territories once established.

Also called the Damara rock-jumper, the rockrunner is the sole member of the monotypic genus Achaetops. It is an agile ground-dweller that runs and hops quickly among boulders, often with its tail cocked. Pairs are strongly territorial and frequently duet with loud, ringing whistles. It was formerly placed with Old World warblers but is now grouped with African warblers.

Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats between rocks
Social Behavior
Usually seen singly or in pairs that maintain year-round territories. Nests are placed low, often in rock crevices or among dense shrubs on rocky slopes. Pairs keep close contact with calls and perform conspicuous tail-cocking while foraging.
Migratory Pattern
Resident
Song Description
A loud, ringing series of clear whistles, often delivered as antiphonal duets by a pair. Calls carry well across rocky valleys and may include sharp, piping notes when alarmed.
Plumage
Grey-brown upperparts with fine streaking, warm rufous rump and tail, and buff underparts that may show slight mottling on the breast. The tail is often held cocked and appears bright rufous in contrast with the back.
Diet
Primarily small arthropods such as insects and spiders, gleaned from rock surfaces, leaf litter, and shrubs. It probes into crevices and under stones, and will chase prey on foot with quick, agile movements. Occasionally takes small larvae and other invertebrates found under debris.
Preferred Environment
Forages on rocky ground, among boulders, and in low shrubbery on slopes and along dry riverbeds. Often searches near rock crevices and ledges that offer both prey and cover.
