River Otter Recorded in New York City's Bronx River for First Time in Over 100 Years
Just the facts
Wildlife Conservation Society researcher RJ Hawkins documented a North American river otter in the Bronx River via motion-activated camera footage in June 2026. The recording marks the first confirmed sighting of a river otter in the Bronx River since the early 1900s, when severe water pollution, habitat destruction, and fur trapping eliminated local populations. Conservation officials attributed the species' return to decades of water cleanup initiatives and environmental protections under the Clean Water Act, which previously facilitated the return of beavers to the river in 2007. Bronx Zoo Director Craig Piper highlighted the discovery as a key indicator of ecological recovery in New York City's primary freshwater river.
