### Identification The Bank Vole is a charismatic, chestnut-red rodent that brings a splash of warmth to the forest floor. Measuring 9–11 cm with a tail roughly half its body length (about 5 cm), it is easily distinguished from the grey-brown Field Vole (*Microtus agrestis*) by its rich reddish-brown mantle and creamy-white underbelly. Look closely at the head: it possesses a blunter, more rounded muzzle than a mouse, with prominent, furry ears that peek out from its coat—unlike the Field Vole, whose ears are almost entirely hidden in shaggy fur. Its eyes are dark, bright beads, reflecting a high-energy lifestyle.
### Habitat & Range This species is the quintessential woodland dweller, found across Europe and into Western Siberia. It thrives in deciduous forests, dense hedgerows, and scrubland where thick leaf litter and brambles provide cover. While it avoids open grasslands, you’ll often find it at the "edge" zones where forest meets field. They are particularly fond of bankings (hence the name) where the soil is friable enough for shallow tunneling.
### Behaviour Unlike many secretive rodents, the Bank Vole is active both day and night, making it a joy for patient observers. They move with a distinctive "hopping" gait and are surprisingly bold. They are highly social but territorial, living in loose colonies with complex overlapping home ranges. In the field, listen for their faint, metallic "chirps" during territorial disputes. During the breeding season (April to September), females can produce up to five litters, leading to late-summer population explosions.
### Diet The Bank Vole is a discerning forager. While it eats green leaves and grasses, it prefers high-energy snacks like hazelnut kernels, hawthorn berries, and fungi. A classic field sign is a hazelnut shell with a neat, circular hole gnawed into it, with visible tooth marks around the rim—a "signature" of their presence.
### Fascinating Fact While most voles are strictly ground-dwellers, the Bank Vole is a remarkably agile climber. It isn't unusual to spot one four or five feet off the ground in a hazel bush or bramble patch, expertly balancing as it harvests ripe berries or nuts!
