In these three photos, two river otters swim downstream in the Mendenhall River on Sunday, March 7. The pair apparently spotted a juvenile bald eagle on the river's edge and stopped to investigate. Otters travel together and operate as a social unit but do not cooperate in hunting or share what is caught. They travel over a wide area, and apparently there are no exclusive territories. Fighting among otters is extremely rare, although they are wary of strange individuals.
