Eurasian Beaver

Castor fiber

Identification

A large semi-aquatic rodent with a broad flattened tail. Chewed branches and characteristic cut stems can be easier to find than the animal itself.

When to look

Resident, commonly most active around dusk and at night. The feeding and building evidence can remain visible when animals are hidden.

Where to look

Rivers, streams, lakes and adjoining bankside vegetation provide water, food and shelter. Suitable woody plants are especially valuable in winter.

Behaviour and ecology

Food and nutrition

Entirely plant-based, including herbs, leaves and bark. It does not need fish despite sharing waterways with fish-eating mammals.

Breeding and life cycle

Family groups occupy bank burrows or lodges, with young remaining alongside their parents before dispersing.

A closer look

By cutting vegetation and sometimes building dams, beavers can alter water levels and create habitat used by many other organisms.

Observation and photography

Watch quietly from an existing route without approaching a lodge. Do not dismantle structures or interfere with banks and feeding trees.

Sources and further reading

Watch from a safe distance, leave animals an escape route and never feed or bait them. Keep away from dens and young. Follow local guide and reserve instructions; sightings cannot be guaranteed.
