Little is known about the visitation patterns of Lontra canadensis (Nearctic river otter) at latrines. We used remote camera and video camera systems manufactured by TrailMaster® to determine when Lontra canadensis (river otters) occupying riverine habitats in Pennsylvania and Maryland visit latrines, what the group composition is during visits, and if either variable changes by season. We documented 173 visits to latrines by river otters. The majority of visits (102) were by single river otters. One hundred fifty of the total visits occurred at night. Most (111) lasted <1 min. The largest peak in visitation to latrines occurred immediately prior to and during the breeding season (February/March).
