Corvus dauuricus
In 3 days <5% in a week ~10%
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 →

Any time of year
In every month with enough records, under 5% of wildlife watchers report a Daurian Jackdaw in Sendai on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Daurian Jackdaw is recorded against all the birds logged in Sendai (6 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.
