The short-tailed field vole, short-tailed vole, or simply field vole (Microtus agrestis), is a grey-brown vole, around 10 cm in length, with a short tail. It is one of the most common mammals in Europe, with a range extending from the Atlantic coast to Lake Baikal. These voles are found in moist grassy habitats, such as woodland, marsh or on river banks. Although they make shallow burrows, they usually build nests above ground. They are an important food source for owls and some other predators and their population size tends to peak and trough cyclically. Field voles breed prolifically, mainly in summer, but often all year round, even under snow. Females produce up to seven litters a year, each averaging from four to six young which are weaned after about fourteen days. The short-tailed field vole is both widespread and common and is listed as being of "Least Concern" by the IUCN.
The short-tailed field vole is a small, dark brown rodent with a short tail, distinguishable from the closely related common vole (Microtus arvalis) by its darker, longer and shaggier hair and by its more densely haired ears. The head and body length varies between 8 and 13 centimetres... Wikipedia →

With luck
About 10% of wildlife watchers report a Field Vole sighting in Snowdonia National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 15 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June and September
In those months about 20% of wildlife watchers report a Field Vole in Snowdonia National Park on a given day, against under 5% in August and October–May, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Field Vole sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Field Vole sightings, Snowdonia National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Cairngorms National Park (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Field Vole is recorded against all the mammals logged in Snowdonia National Park (5 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.
