The Cape grassbird or Cape grass warbler is an African warbler found in southern Africa. It is the only species placed in the genus Sphenoeacus.
Region
Southern Africa
Typical Environment
Occurs chiefly in South Africa, Lesotho, and Eswatini, favoring fynbos-covered slopes, montane and foothill grasslands, bracken and protea thickets, and dense coastal scrub. It uses ecotones and rank, regenerating vegetation after fire, where tall stems provide song perches. Birds keep close to cover, moving through tangles of grass and shrubs. It also occurs along forest edges and rocky hillsides with dense ground cover.

The Cape grassbird is the only species in the genus Sphenoeacus and is characteristic of South Africa’s fynbos and montane grasslands. It often sings from prominent perches despite otherwise skulking habits in dense vegetation. Its long, graduated tail and rich, ringing song help distinguish it from other warbler-like birds. It is generally resident year-round within its southern African range.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats, low and bouncing over vegetation
Social Behavior
Usually found singly or in pairs that hold territories, especially during the breeding season. Nests are placed low in dense grass or shrub cover, and both adults remain close to cover when alarmed. Breeding occurs in the austral spring and summer, with pairs often advertising territories from exposed perches.

Song Description
A loud, ringing series of rich phrases and trills delivered from the tops of shrubs or tall stems. Calls include harsh churrs and sharp chits given when agitated.
