National Geographic Sea Bird continued its southward migration last night. Dawn’s first light revealed hundreds of common dolphins off the port bow; close your eyes and hear the whooshes and swooshes of the dolphins moving through the water. Later in the morning, numerous groups of bottle-nosed dolphins rode the ship’s bow wave as we cruised the Sea of Cortez. Isla Danzante is the day’s destination. We spent the afternoon hiking, kayaking, snorkeling, and paddle boarding.
