Bottlenose dolphins reach the northern edge of their East Coast range in New York, and the state’s 26 records since 2000 reflect that edge. Fourteen of them come from Suffolk County on Long Island, with a handful more from Nassau, Queens, and Kings counties. One record sits oddly inland in Putnam County, a reminder that a single report can mark a wandering animal or a stranding rather than any resident group.
Reports crest in July and August, with smaller rises in May and December. That summer peak tracks two things at once: dolphins moving into the New York Bight as the water warms, and the huge seasonal jump in people on beaches and boats who are there to notice them. Records show where observers were looking, not a headcount of dolphins.
Fire Island National Seashore is the only named place with more than one record, which fits a species that patrols the surf zone along barrier islands. NatureServe ranks the species Vulnerable (S3) in New York, so each verified report here carries real weight in tracing how far north these dolphins range.
