Beaver (Castor canadensis) gnawing a cottonwood tree into lengths. It is doing this so that it can carry the pieces back to its lodge. The beaver uses the lengths of wood to build a dam and a lodge, a closed nest-like structure with underwater entrances. The beaver eats the bark and growing wood of the trees it fells. It is a large rodent, reaching over a metre in length including its flattened paddle-like tail. Photographed in Wyoming, USA, in October.
