Rare
Under 5% of wildlife watchers report a Brown-headed Thrush sighting in Taichung on a given day, based on 114 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 121 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March and December–January
In those months about 10% of wildlife watchers report a Brown-headed Thrush in Taichung on a given day, against under 5% in February and April–November, the lowest months. Those are among Taichung's driest months, with about 60 mm of rain a month against 330 mm in August.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Brown-headed Thrush 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.
7th of 13
Of the 13 cities where we can rate Brown-headed Thrush sightings, Taichung ranks 7th at under 5%. The best odds are in Kaohsiung (Taiwan, about 20%), Sendai (Japan, about 10%) and Xiamen City (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown-headed Thrush is recorded against all the birds logged in Taichung (114 verified sightings), 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.
