The Taiwan bush warbler (Locustella alishanensis) is a species of Old World warbler in the family Locustellidae. It is found only in Taiwan. Its natural habitat is undergrowth and grassland 1,200–3,000 m (3,900–9,800 ft) in elevation. It was first recorded in 1917 and named as a distinct species in 2000. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
This bush warbler was first recorded from Alishan in 1917. At first, it was thought to be a population of Bradypterus luteoventris. In 1952, Jean Théodore Delacour placed it within subspecies idoneus of B. seebohmi (now split into several species). Later authorities placed it in subspecies melanorhynchus. In the late 1980s, its song was found to be very distinctive, unlike other related species. In 2000, Pamela C. Rasmussen, Philip D. Round, Edward C. Dickinson and Frank Rozendaal described the population as a distinct species, Bradypterus alishanensis, based on its distinctive song and morphological observations. It was later transferred to the genus Locustella. A 2015 study concluded that it was the sister taxon of the russet bush warbler (Locustella mandelli) species... Wikipedia →

Possible
About 30% of wildlife watchers report a Taiwan Bush-Warbler sighting in Taroko National Park on a given day, based on 818 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 147 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 70% of wildlife watchers report a Taiwan Bush-Warbler in Taroko National Park on a given day, against under 5% in November to February, the lowest months.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Taiwan Bush-Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Taiwan Bush-Warbler sightings: about 30% of wildlife watchers there report one on a given day.
Same order: Passeriformes
The closest relatives of the Taiwan Bush-Warbler that you can see in Taroko National Park (order Passeriformes, Perching Birds) are Large-billed Crow (about 70%), Taiwan Yuhina (about 70%) and White-eared Sibia (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Taiwan Bush-Warbler is recorded against all the birds logged in Taroko National Park (818 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
