The complete county distribution, spread across 2 Alabama counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Alabama’s narrow Gulf coast concentrates bottlenose dolphin watching around Dauphin Island, Mobile Bay, and the nearshore water off Gulf State Park and Bon Secour. From shore, search beyond breaking waves and around tidal passes for dorsal fins, coordinated surfacing, or birds feeding over the same school of fish.

Dolphins are reported in every month, with a June high in this record set. Calm seas and low glare matter more than the calendar: morning viewing often makes subtle blows and fin arcs easier to pick out without approaching or disrupting a traveling group.
