ムナフセッカ

The cloud cisticola (Cisticola textrix) is a small passerine bird in the family Cisticolidae native to the grasslands of South Africa and Lesotho. It inhabits short open grasslands, karoo scrub, and montane grasslands at elevations up to 3,000 meters in the Drakensberg highlands, where males perform conspicuous high-altitude song flights that give the species its common name. The plumage is cryptically streaked brown and buff above, helping the bird blend into its grass habitat, with a short tail and fine bill adapted for insectivory. Like other cisticolas, C. textrix constructs a characteristic purse-shaped woven grass nest hidden deep within tussock grass. The species is endemic to southern Africa, with the core range centered on the South African highveld and Lesotho highlands. It feeds on small invertebrates gleaned from grass stems and the ground surface. Cloud cisticola populations face pressure from conversion and degradation of native grasslands through overgrazing, agricultural expansion, and inappropriate burning regimes affecting the open grassland habitats it requires throughout its southern African range.
