The common crane (Grus grus), also known as the Eurasian crane, is a bird of the family Gruidae, the cranes. A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane (Grus virgo) and the Siberian crane (Leucogeranus leucogeranus) that only are regular in the far eastern part of the continent. Along with the sandhill crane (Antigone canadensis), demoiselle crane and the brolga (Antigone rubicunda), it is one of only four crane species not currently classified as threatened with extinction or conservation dependent on the species level. Despite the species' large numbers, local extinctions and extirpations have taken place in part of its range, and an ongoing reintroduction project is underway in the United Kingdom.
The first formal description of the common crane was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Ardea grus. The current genus Grus was erected by the French zoologist Mathurin Jacques Brisson in 1760. Grus is the Latin word for a "crane". The species is considered to be monotypic: no subspecies are recognised.

Rare
Under 5% of wildlife watchers report a Common Crane sighting in Hamburg on a given day, based on 57 verified sightings from GBIF citizen-science data. It is the 62nd most-seen of the 118 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.
January and September–November
In those months about 10% of wildlife watchers report a Common Crane in Hamburg on a given day, against under 5% in February–August and December, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Common Crane sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 20
Of the 20 cities where we can rate Common Crane sightings, Hamburg ranks 6th at under 5%. The best odds are in Helsinki (Finland, about 10%), Berlin (Germany, about 10%) and Novosibirsk (Russia, about 10%).
Same order: Gruiformes
The closest relatives of the Common Crane that you can see in Hamburg (order Gruiformes, Cranes, Rails, and Allies) are Common Moorhen (about 50%) and Eurasian Coot (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Crane is recorded against all the birds logged in Hamburg (57 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.
