Taiwan Bush Warbler
Locustella alishanensis
- langka
- 55 km/h
- Risiko rendah
A voice in the dwarf bamboo, almost never a bird. Heard ringing across Taiwan's alpine slopes, it gives up its silhouette only for the patient.
- Populasi
- Global population unquantified; Taiwan's (the entire range) breeding population estimated at 10,000-100,000 pairs with a stable trend
- Habitat
- High-elevation grassland, shrubland, and bamboo/fern/grass undergrowth near the treeline in Taiwan's mountains (roughly 1,000-3,680 m, occasionally down to 100 m in winter); also uses disturbed/arable margins. Does not normally occur in closed forest, though it is described as deciduous/coniferous woodland with thick undergrowth.
- Fakta menarik
- Long lumped with the Russet Bush Warbler complex, the Taiwan Bush Warbler was only recognized as a distinct species in 2000 on the strength of its unique song — a repeated monotone whistle followed by three or four clicks.
- Sebaran
- Endemic to Taiwan; resident year-round in mountain regions, descending to lower elevations in winter. Extent of occurrence approximately 15,400 km².
- Makanan
- Insectivorous; feeds on insects and other small invertebrates gleaned from dense low undergrowth (stomach contents of the type specimen contained insects).
