While Hairy-tailed Moles are solitary animals, Star-nosed Moles live in small colonies. Generally, the latter cause the most damage to the ground. Being excellent swimmers, they prefer areas close to water, although they can be found practically anywhere.
Both species are active all year long. They leave their burrows very rarely, and when they do, it?s at night or under cover of snow in winter. Although their poor eyesight makes them an easy target, their offensive odor repels predators.
