The chestnut-bellied tit (Sittiparus castaneoventris) is a small passerine bird in the tit family Paridae that is endemic to Taiwan. The chestnut-bellied tit was first described by the English ornithologist John Gould in 1863 and given the binomial name Parus castaneoventris. It was formerly considered as a subspecies of the varied tit but was promoted to species status after the publication of a phylogenetic study in 2014.
The species differs from the varied tit in having underparts of a deep chestnut colour. PARUS (Taiwanese satellite family) Birding In Taiwan: Endemic subspecies of Taiwan birds - first impressions Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-bellied Tit sighting in Shanghai on a given day, based on 118 verified sightings from GBIF citizen-science data. It is the 93rd most-seen of the 202 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Chestnut-bellied Tit in Shanghai on a given day, against under 5% in January to November, the lowest months. That is one of Shanghai's driest months, with about 55 mm of rain against 200 mm in June.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Chestnut-bellied Tit sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 14
Of the 14 cities where we can rate Chestnut-bellied Tit sightings, Shanghai ranks 14th at under 5%. The best odds are in Sapporo (Japan, about 80%), Gwangju (South Korea, about 50%) and Sendai (Japan, about 50%).
Same family: Paridae
The closest relatives of the Chestnut-bellied Tit that you can see in Shanghai (family Paridae, Tits, Chickadees, and Titmice) are Cinereous Tit (about 60%) and Yellow-bellied Tit (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chestnut-bellied Tit is recorded against all the birds logged in Shanghai (118 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.
