Reports of this social offshore dolphin concentrate where the continental shelf narrows near Cape Hatteras and the Gulf Stream keeps deep, warm water close to the Outer Banks. In that shelf-edge setting, groups hunt squid well beyond the sounds and estuaries behind the barrier islands.
The state’s month-by-month data shows a sharp spike in January and comparatively few records the rest of the year, a pattern that likely reflects a cluster of strandings or a single well-documented group sighting rather than a true winter concentration of the species.
Pilot whales travel in tight social pods, so one recorded event, whether a sighting or a stranding, can add many records at once. That makes a single month’s spike a poor guide to when the species is actually present off North Carolina versus simply when it was last documented.
