The chestnut-cheeked starling (Agropsar philippensis) is a species of starling in the family Sturnidae. It breeds in Japan and the Russian islands of Sakhalin and Kuriles; it winters in Taiwan, the Philippines and northern Borneo.
The chestnut-cheeked starling was previously placed in the genus Sturnus. It was moved to the resurrected genus Agropsar based on the results of two molecular phylogenetic studies that were published in 2008. Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-cheeked Starling sighting in Tokyo on a given day, based on 134 verified sightings from GBIF citizen-science data. It is the 121st most-seen of the 229 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chestnut-cheeked Starling in Tokyo on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Chestnut-cheeked Starling sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 8
Of the 8 cities where we can rate Chestnut-cheeked Starling sightings, Tokyo ranks 4th at under 5%. The best odds are in Sendai (Japan, about 10%), Sapporo (Japan, about 10%) and Osaka (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Chestnut-cheeked Starling is recorded against all the birds logged in Tokyo (134 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.
