New York’s file on this dolphin is short: 17 records since 2000, and nine of them have no county attached because they came from offshore water. Of the rest, Suffolk County on Long Island holds seven, which fits the geography. Long Island’s south shore and the waters off Montauk are the closest New York comes to the open Atlantic, and that’s where a cold-water dolphin following baitfish would turn up, alive or as a stranding on an ocean beach. Fire Island National Seashore accounts for three of the reports.
The few dated records tilt toward spring, April and May, with a smaller showing in January, a plausible seasonal pass as fish schools shift along the shelf, though with numbers this low a handful of events can bend the whole pattern. NatureServe treats the species as an unranked, nonbreeding visitor in the state, which matches the record: New York is the southwestern fringe of its range, not a stronghold. Every verified report from New York waters is worth more than the small total suggests.
