Beavers do not have a distinct sound that they make. However, they do have body actions that they do that indicate when they feel threatened. They slap their tail on the water or on a solid surface if they sense danger or if they are threatened. When this happens, they usually seek refuge back in their home and stay hidden until they deem it safe enough to go out again. They make slight growling or hissing sounds when angered or provoked. They can also produce grunting or grumbling sounds.
