Likely
About 40% of wildlife watchers report a Collared Bush-Robin sighting in Taroko National Park on a given day, based on 1,437 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 147 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May to August
In those months about 60% of wildlife watchers report a Collared Bush-Robin in Taroko National Park on a given day, against about 10% in January and February, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Collared Bush-Robin sightings with a recorded time, and about 7 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 Collared Bush-Robin sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Collared Bush-Robin is recorded against all the birds logged in Taroko National Park (1,437 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.
