Another beautiful, calm day welcomed the travelers aboard the National Geographic Sea Bird to San Ignacio Lagoon. Our morning on the water was filled with a variety of experiences. There were quiet moments observing the birdlife overhead, including royal terns and white ibis. Then we were back to splashing and chipper exhalations during our encounters with the friendly gray whales. The day was full and rich, ending on a colorful note with our first blue whale sighting and a green flash at sunset as we headed south toward the tropics.
