Otters roll on river banks and leave a musky scent. Dens are dug into banks, with underwater or above ground entrances. Nests are made inside the den out of leaves, sticks, and grass. Otters will often travel overland, far from water. They are active during daylight.
Otters have two to three pups in late spring.
Adult otters can weigh 30 pounds. A family of otters lives in the Eel River near the property I caretake. Every time I walk along the river banks, I find otter tracks. They love nothing better than to chase each other out of the water and up the bank, where they roll around and wrestle. For some reason, dogs seem attracted to otter scent.
