Tanimbar Çalıbülbülü Horornis carolinae

A long-billed brown warbler with a prominent buff eyebrow, a russet cap, a white throat, and a gray underside. An arboreal species that inhabits thick understory of forest, edges, bamboo thickets, and scrub. Restricted to Yamdena in the Tanimbar Islands. Unstreaked upperparts separate it from the other brown warbler-like birds in range, Tawny Grassbird and Zitting and Golden-headed Cisticolas. Distinctive song, characteristic of bush warblers, begins with a building, ascending three-part whistle with a significantly drawn-out third note, before jumbled fourth note: “tu-tu-tuooooo-chyop.” Also gives abrupt “chup” calls.
