A group of cownose rays was observed swimming in Newtown Creek last weekend, marking a significant moment for the waterway that has long been known for its pollution. The estuary, which forms a boundary between Brooklyn and Queens in New York City, has historically been one of the most contaminated industrial sites in the United States.

The sighting of the rays, described as unusual by local environmental experts, was highlighted by Willis Elkins, executive director of the Newtown Creek Alliance. Elkins noted that groups of rays are typically drawn to areas where food is abundant, suggesting improving ecological conditions. “The whole group swimming as one was really awesome to witness,” he said.

Newtown Creek was designated a federal Superfund site in 2010, which initiated extensive cleanup operations aimed at mitigating decades of industrial waste and sewage pollution. Since then, environmental advocates and officials have recorded a gradual rebound in local biodiversity.

In recent years, wildlife sightings along the creek have included oysters, clams, bass, moonfish, swans, egrets, and robins, indicating a positive shift toward ecological recovery. Elkins remarked that 2026, in particular, has been notable for increased wildlife activity. He pointed to the unexpected appearance of horseshoe crabs in a tributary known for water quality challenges and observed the presence of eels in the creek during the same year.

These developments, while preliminary, may signal broader improvements in water quality and habitat restoration efforts. However, despite such signs of progress, Newtown Creek remains an area of ongoing environmental concern and active remediation. The continued presence and diversity of aquatic and avian species will likely be key indicators for monitoring the success of the cleanup initiatives moving forward.
