Bottlenose dolphin records in Virginia lean almost entirely on GBIF data, 1,417 records against just 7 from iNaturalist photos. That imbalance is typical for a marine mammal: most sightings come from boat-based surveys, stranding responses, and research cruises rather than someone snapping a photo from shore, even though dolphins are easy to recognize when they surface.

The refuges tied to these records, Chincoteague and Back Bay, sit right on the barrier-island coast, and most reports actually trace to the Chesapeake Bay and adjacent Atlantic waters those refuges border, not the refuge land itself. Reports climb through summer, peaking in August, which fits the coastal population’s warm-season presence in Virginia waters before many dolphins shift south or farther offshore for winter.

NatureServe doesn’t assign this wide-ranging marine species a Virginia rank at all, marking it Not Applicable rather than tracking a state-level conservation status.
