Dolphins Use New York Harbor as a Feeding Ground, Study Finds



When you think of the New York Harbor, you might imagine boats, skyscrapers, a noisy traffic on the nearby streets of NYC. What you may not expect to find are dolphins. But according to a newly released study from Wildlife Conservation Society, the New York Harbor is a popular feeding ground for bottlenose dolphins from spring through fall.

Researchers placed underwater listening devices in six separate locations around Brooklyn, Queens, Staten Island and New Jersey. They monitored the activity between April and October from 2018 to 2020. The dolphins were heard clicking rapidly, called “foraging buzzes,” revealing extensive feeding activity.

“We’ve been seeing dolphins regularly,” said Howard Rosenbaum, director of the WCS Ocean Giants Program and a senior conservation scientist for the New York Aquarium, as reported by Inside Climate News. “I think what’s interesting is that you can see them quite frequently, if you’re on the beach. It’s not all the time, and it might not be the right time of the day when you’re looking, but we do see them regularly.”

The study was initially started to study whales in the New York-New Jersey Harbor Estuary, but the researchers ended up hearing a lot of dolphin activity on the acoustic monitoring devices. The area is quite rich in biodiversity, with whales, dolphins and more than 200 species of fish.

“I think people in general don’t associate the waters off New York with being diverse, ecological, ecologically rich, important areas for species like marine mammals,” Rosenbaum said. “Over the last decade or so, we’re seeing some pretty important changes here in terms of certain species, like dolphins and whales, increasingly using these habitats as a suitable prey base for these animals.”
