Distribution and habitat

Common Shrews live in Common shrew across Britain, Europe, and western Russia in woodlands, gardens, and grassland. Preferred habitat includes woodlands, gardens, and grassland across europe. Across Europe, population density reflects prey availability, water access, and human disturbance. Protected areas and wildlife corridors remain essential for long-term persistence.

Physical traits and behaviour

Common Shrews typically reach about 0.08 m in length and 0.01 kg in weight, with top speeds near 8 km/h. The tiny insectivore with a fierce appetite. Daily activity, social structure, and seasonal movements reflect pressures in their native environment.

Diet and ecological role

Common Shrews feed on insectivore — insects, worms, slugs, and spiders. Foraging shifts with season and local abundance. As mammals, they influence food webs — controlling prey, dispersing seeds, or shaping habitat through feeding and movement.

Conservation and coexistence

Listed as Least Concern on the IUCN Red List. Habitat loss, hunting, and climate change threaten many populations. Responsible ecotourism and community conservation help in parts of their range. Never approach or feed wild common shrews.

Human interest and research

Common Shrews feature in folklore, tourism, and scientific study worldwide. Ongoing research tracks population trends, genetics, and responses to environmental change — data that guides national protection policies.

Did you know? Common Shrew facts

• Common shrews are tiny mammals that must eat every few hours to survive.
• No — shrews are insectivores in a separate order from rodents.
• They reduce activity in winter but do not true hibernate.
• Conservation: Least Concern.

Diet & feeding

Common Shrew feeds primarily as a insects, worms, slugs. Shrews lose weight overnight without food and may eat 80–90% of body weight daily.

Adaptations

• Shrews lose weight overnight without food and may eat 80–90% of body weight daily.
• Saliva toxins subdue prey but are harmless to humans.

Behaviour & ecology

• Shrews lose weight overnight without food and may eat 80–90% of body weight daily.
• Saliva toxins subdue prey but are harmless to humans.

Communication

• Common Shrew uses scent, posture, and vocal signals to mark territory and coordinate social behaviour.
• Communication intensity often peaks during breeding seasons and territorial disputes.
