Grand Teton National Park Report
The 1996 project was a continuation of the study begun in 1995 - to obtain information on movements, sociability, and activity patterns of river otters in the Oxbow region of the Snake River within Grand Teton National Park. Particular emphasis was on nocturnal patterns as documented by automatic cameras activated by buried treadleswitches in places otters were known to frequent, such as latrines, resting sites and feeding sites. Daytime activity was monitored both by the cameras and by routine canoe patrols. Field work was carried out July 5- August 5.
