Rare
Under 5% of wildlife watchers report a Brown-headed Thrush sighting in Tokyo on a given day, based on 880 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 229 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
December to April
In those months about 10% of wildlife watchers report a Brown-headed Thrush in Tokyo on a given day, against under 5% in May to November, the lowest months.
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.
5th of 13
Of the 13 cities where we can rate Brown-headed Thrush sightings, Tokyo ranks 5th at under 5%. The best odds are in Kaohsiung (Taiwan, about 20%), Sendai (Japan, about 10%) and Xiamen City (China, about 10%).
Same genus: Turdus
The closest relatives of the Brown-headed Thrush that you can see in Tokyo (genus Turdus, Typical Thrushes) are Dusky Thrush (about 30%) and Pale Thrush (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Brown-headed Thrush is recorded against all the birds logged in Tokyo (880 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.
