The Bronx River Alliance and Bronx Zoo are asking the public to help name a North American river otter recently spotted in New York City’s Bronx River, the first confirmed sighting in about 100 years.

Bronx Zoo scientist RJ Hawkins photographed the otter while monitoring wildlife along the 23-mile river. The return of the otter signals improving conditions in a waterway that was once heavily polluted and considered one of the most neglected urban rivers in the United States.

For the past 25 years, restoration efforts by public agencies, nonprofits, volunteers, and conservation groups have worked to clean up the Bronx River. These efforts previously led to the return of beavers in 2007, and Hawkins also observed a mink this summer. River otters are indicators of healthy freshwater ecosystems, relying on clean water and good habitat. The Bronx River Alliance, Wildlife Conservation Society, and other partners believe the otter’s appearance demonstrates the success of ongoing conservation work.

While one sighting doesn’t confirm a full population has returned, it shows the river can now support native wildlife. People can vote for the otter’s name, Nessie, Ruthie, or Morgan, by commenting on Instagram until September 29. The winning name will be announced October 1.
