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 →

With luck
About 10% of wildlife watchers report a Chestnut-bellied Tit sighting in Kitakyushu on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 20th most-seen of the 39 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Chestnut-bellied Tit in Kitakyushu on a given day, against about 10% in February–May and October–November, the lowest months. January and June–August have too few records to rate.
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.
11th of 14
Of the 14 cities where we can rate Chestnut-bellied Tit sightings, Kitakyushu ranks 11th at about 10%. The best odds are in Sapporo (Japan, about 80%), Gwangju (South Korea, about 50%) and Sendai (Japan, about 50%).
GBIF citizen-science records
It is estimated from how often the Chestnut-bellied Tit is recorded against all the birds logged in Kitakyushu (9 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.
