The northern nutcracker (Nucifraga caryocatactes), previously known as the spotted nutcracker and Eurasian nutcracker, is a passerine bird in the crow family Corvidae. It is slightly smaller than the Eurasian jay but has a much larger bill and a slimmer looking head without any crest. The feathering over its body is predominantly chocolate brown with distinct white spots and patches. The wings and upper tail are black with a greenish-blue gloss.
The northern nutcracker is one of four species of nutcracker currently accepted. The southern nutcracker (Nucifraga hemispila) and the Kashmir nutcracker (Nucifraga multipunctata) were formerly considered as subspecies of the northern nutcracker. The species complex was known by the English name "spotted nutcracker". The fourth and most distinct member of the genus, Clark's nutcracker (Nucifraga columbiana), occurs in western North America.
The northern nutcracker was one of many species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, where it was given the binomial name Corvus caryocatactes. It was later assigned to the genus Nucifraga that was erected by Mathurin Jacques Brisson in... Wikipedia →

Rare
Under 5% of wildlife watchers report a Eurasian Nutcracker sighting in Helsinki on a given day, based on 71 verified sightings from GBIF citizen-science data. It is the 167th most-seen of the 233 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Eurasian Nutcracker in Helsinki on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Eurasian Nutcracker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Eurasian Nutcracker sightings, Helsinki ranks 3rd at under 5%. The best odds are in Novosibirsk (Russia, about 10%) and Yekaterinburg (Russia, about 10%).
Same family: Corvidae
The closest relatives of the Eurasian Nutcracker that you can see in Helsinki (family Corvidae, Crows, Jays, and Magpies) are Hooded Crow (about 80%), Eurasian Magpie (about 30%) and Eurasian Jackdaw (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eurasian Nutcracker is recorded against all the birds logged in Helsinki (71 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.
