Distribution

Region

South Atlantic (Tristan da Cunha archipelago)

Typical Environment

Restricted to Inaccessible Island, where it occupies coastal slopes, tussock grasslands, fern-bush, and patches of Phylica arborea woodland. It forages from shoreline vegetation up to the inland plateau, using dense cover for nesting and protection. The species uses a mosaic of habitats created by wind exposure and salt spray, shifting among them seasonally as food peaks. It nests low in vegetation and readily exploits seed-rich areas after gales.

Useful to know

Also known as the Inaccessible bunting, this finch is endemic to Inaccessible Island in the Tristan da Cunha group and belongs to the tanager family (Thraupidae). It famously occurs in two bill-size morphs that partition food resources, an island example of ecological divergence. The island is part of the Gough and Inaccessible Islands World Heritage Site and remains free of invasive mammalian predators. Any introduction of predators would pose a serious threat due to its tiny range.

Behaviour

Temperament

wary but curious; often quietly active in low vegetation

Flight Pattern

short rapid wingbeats with brief low, direct flights between cover

Social Behavior

Typically seen in pairs or small family groups, becoming more dispersed during breeding. Monogamous pairs build cup nests low in dense grasses or shrubs. Clutches are small, and both parents contribute to feeding the young. Outside breeding, loose foraging groups form where seeds are abundant.

Migratory Pattern

Resident

Song Description

A thin, high-pitched twittering series of trills and chips, delivered from low perches. Calls include soft tseep notes and sharper ticks when alarmed.
