Corvus dauuricus
In 3 days ~10% in a week ~20%
The Daurian jackdaw (Coloeus dauuricus) is a bird in the crow family, Corvidae, native to eastern Asia. It is closely related to the western jackdaw. The name derives from the Dauria region of eastern Russia. Around 32 cm (13 in) in length, the Daurian jackdaw is about the same size as or slightly smaller than the western jackdaw, with the same proportions and identical habits. The principal difference lies in the plumage, but many adults have large areas of creamy white on the lower parts extending up around the neck as a broad collar. The head, throat, wings, and tail are glossy black and the ear coverts are grizzled grey. Darker adults and young birds resemble western jackdaws, though Daurian jackdaws have black irises, unlike the distinctive grey-white irises of the Eurasian jackdaw. The only other pied corvid species inhabiting the same region is the Chinese collared crow (Corvus torquatus), but as this is a much larger bird (about the same size or slightly larger than the carrion crow), confusion is unlikely to occur.
The Daurian jackdaw ranges from the southern part of eastern Siberia, south to Mongolia and throughout much of China... Wikipedia →

Rare
Under 5% of wildlife watchers report a Daurian Jackdaw sighting in Tianjin on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 121 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October to December
In those months about 10% of wildlife watchers report a Daurian Jackdaw in Tianjin on a given day, against under 5% in January to September, the lowest months. Those are among Tianjin's driest months, with about 15 mm of rain a month against 160 mm in July.
2nd of 3
Of the 3 cities where we can rate Daurian Jackdaw sightings, Tianjin ranks 2nd at under 5%. The best odds are in Beijing (China, about 10%).
Same family: Corvidae
The closest relatives of the Daurian Jackdaw that you can see in Tianjin (family Corvidae, Crows, Jays, and Magpies) are Oriental Magpie (about 90%) and Azure-winged Magpie (about 90%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Daurian Jackdaw is recorded against all the birds logged in Tianjin (18 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.
