Beavers are territorial and will attack outsiders.

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (A)

Beavers defend defined territories around their lodge and dam to protect vital resources and their family group. They establish and maintain scent-marked boundaries and use warning signals like tail-slaps and vocalizations to deter outsiders. When a boundary is crossed or an intruder persists, beavers can respond with aggression, including charging or biting with their strong incisors to drive the visitor away. This defensive behavior reflects their need to safeguard food caches, nesting sites, and the safety of their family, so it’s accurate to say they will attack outsiders in defense of their territory. In a rehab or field setting, give beavers ample space, avoid approaching lodges or dams, and handle with extreme care, recognizing their strong drive to defend their territory.
