The coal tit (Periparus ater) is a passerine bird in the tit family, Paridae. It is a widespread and common resident breeder in forests throughout the temperate to subtropical Palearctic, including North Africa. The black-crested tit is now included in this species.
This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Linnaeus' primary reference was his earlier Fauna Svecica, whose pre-binomial name Parus capite nigro: vertice albo, dorso cinereo, pectore albo ("black-headed tit with white nape, ash-grey back, white breast") became Parus ater. This name – meaning "dusky-black tit" – was simply adopted from older ornithological textbooks, ultimately going back to Conrad Gessner's 1555 Historia animalium. He gave no type locality except "Europe", but his original description refers to the population inhabiting Sweden (which is consequently included in the nominate subspecies today). The current genus name, is Ancient Greek peri plus the pre-existing genus Parus. The specific ater is Latin for "dull black".
The coal tit is placed in the genus Periparus, which was formerly widely considered a subgenus of Parus... Wikipedia →

With luck
About 10% of wildlife watchers report a Coal Tit sighting in Ulaanbaatar on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 63 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
October and December–January
In those months about 20% of wildlife watchers report a Coal Tit in Ulaanbaatar on a given day, against under 5% in February, the lowest month. Those are among Ulaanbaatar's driest months, with about 5 mm of rain a month against 70 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Coal Tit sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
25th of 66
Of the 66 cities where we can rate Coal Tit sightings, Ulaanbaatar ranks 25th at about 10%. The best odds are in Sapporo (Japan, about 50%), Madrid (Spain, about 50%) and Manchester (United Kingdom, about 40%).
Same family: Paridae
The closest relatives of the Coal Tit that you can see in Ulaanbaatar (family Paridae, Tits, Chickadees, and Titmice) are Great Tit (about 80%), Azure Tit (about 50%) and Willow Tit (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Coal Tit is recorded against all the birds logged in Ulaanbaatar (13 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.
