Overview
- A motion-activated camera overseen by the Wildlife Conservation Society’s Bronx Zoo Education Department captured a North American river otter on June 23, 2026, marking the first documented sighting in the Bronx in roughly 100 years.
- The camera was deployed by scientist R.J. Hawkins, who reviewed the images and said he was stunned by the discovery; WCS confirmed the photo after review.
- Bronx River stewards and zoo officials credited decades of public‑private restoration work by groups such as the Bronx River Alliance and WCS for improving habitat and reducing pollution that helped make the river more hospitable.
- Researchers cautioned that a single camera-trap image does not prove an established resident population and noted the Bronx River is still not classified safe for swimming or drinking, so continued monitoring and cleanup remain needed.
- River otters are ecological indicators because they require clean water, abundant fish and intact riparian corridors, and experts say the sighting—like beavers’ return in 2007—offers a measurable sign of staged ecological recovery and a reason to watch for more wildlife returns.
