The yellow-necked mouse (Apodemus flavicollis), also called yellow-necked field mouse or yellow-necked wood mouse, is closely related to the wood mouse, with which it was long confused. It was only recognised as a separate species in 1894. It differs in its band of yellow fur around the neck and in having slightly larger ears and usually being slightly larger overall. Around 100 mm in length, it can climb trees and sometimes overwinters in houses. It is found mostly in mountainous areas of southern Europe, but extends north into parts of Scandinavia and Britain. It facilitates the spread of tick-borne encephalitis to humans and is a reservoir species for the Dobrava virus, a hantavirus that is responsible for causing haemorrhagic fever with renal syndrome.
Apodemus ponticus is probably a synonym of Apodemus flavicollis. The former is found in the former Soviet Union with the boundary between the two being the political boundary between Russia and Western Europe. For many years direct comparison of the two species was not possible because of political tensions but it is now accepted that they are in reality the same species.

With luck
About 10% of wildlife watchers report a Yellow-necked Field Mouse sighting in Helsinki on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 23 mammals 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.
January–February and November
In those months about 20% of wildlife watchers report a Yellow-necked Field Mouse in Helsinki on a given day, against under 5% in March, the lowest month.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Yellow-necked Field Mouse sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 cities where we can rate Yellow-necked Field Mouse sightings, Helsinki has the highest daily chance: about 10%. Next come Berlin (Germany, about 10%) and Hamburg (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow-necked Field Mouse is recorded against all the mammals logged in Helsinki (41 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.
