The bank vole (Clethrionomys glareolus) is a small vole with red-brown fur and some grey patches, with a tail about half as long as its body. A rodent, it lives in woodland areas and is around 100 millimetres (3.9 in) in length. The bank vole is found in much of Europe and in northwestern Asia. It is native to Great Britain but not to Ireland, where it has been accidentally introduced, and has now colonised much of the south and southwest.
The bank vole lives in woodland, hedgerows and other dense vegetation, such as bracken and bramble. Its underground chamber is lined with moss, feathers and vegetable fibre and contains a store of food. It can live for eighteen months to two years in the wild and over 42 months in captivity and is mostly herbivorous, eating buds, bark, seeds, nuts, leaves and fruits and occasionally insects and other small invertebrates. It readily climbs into scrub and low branches of trees although it is not as versatile as a mouse. It breeds in shallow burrows, the female rearing about four litters of pups during the summer.
The bank vole is a small rodent resembling a mouse when young but developing a stouter body, a slightly rounder head with... Wikipedia →

Possible
About 20% of wildlife watchers report a Bank Vole sighting in Białowieża National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 18 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May–June and October
In those months about 30% of wildlife watchers report a Bank Vole in Białowieża National Park on a given day, against under 5% in July, September and November–March, the lowest months.

GBIF citizen-science records
It is estimated from how often the Bank Vole is recorded against all the mammals logged in Białowieża National Park (9 verified sightings from 2019 to 2026), 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.
