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 Daegu on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 29th most-seen of the 47 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Chestnut-bellied Tit in Daegu on a given day, against under 5% in February and October, the lowest months. That is one of Daegu's driest months, with about 25 mm of rain against 260 mm in July. April, July–August and December 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.
13th of 14
Of the 14 cities where we can rate Chestnut-bellied Tit sightings, Daegu ranks 13th 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 Daegu (8 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.
