They are more active at night in summer and more active during the day in winter.
Otters are active throughout the year and are primarily nocturnal. Though they are primarily active at dusk and throughout the night, they have been seen during mid day. Otter dens normally are burrows that have been appropriated from some other animal and renovated by the otter. The River Otter is associated with river, lake, pond, or marsh habitats but may make extensive overland excursions from one such habitat to another. In Oregon, River Otters are mostly found west of the Cascade Range but have been found in eastern Klamath County and in Deschutes, Wallowa, and Malheur counties. They sometimes team up with coyotes to flush rodents from cover. Some badgers have demonstrated that they will tolerate a fox or coyote sharing the same den. In 1871, a lost Canadian boy shared a den with a badger, which at first tried to drive him away, and then appeared to adopt him by bringing him food. Juveniles may emerge from the den as early as 2 months but stay with their mother until 5 to 6 months old. The young badgers stay in their grass-lined den, nursing until 3 months of age. In springtime, female badgers give birth to litters ranging from one to five pups. Wintering dens can sometimes be found in woodlands, where the frost does not penetrate as deeply. They can stay underground for weeks at a time, but they come out to hunt occasionally as they do not store food. Both serve in locating food species, which are usually rodents in underground dens.īadgers have been known to plug the exit holes of prey species before the badger tunnels underground to capture the prey. The long claws serve to loosen the soil and pass it backwards where the hind feet kick the soil out behind the digging animal. Badgers do not hibernate but they do sleep for extended periods especially during extended periods of cold weather and deep snow. Badgers have excellent senses of hearing and smell. They are largely nocturnal but occasionally may be seen abroad during daylight hours. They require soils that allow the excavation of den sites and support burrowing prey species like ground squirrels. American Badgers are generally found in grassland, desert, dry forest, and agricultural areas.
