It was our last full day at sea before reaching South Georgia. We crossed the Antarctic Convergence Zone today and it is now noticeably colder, with a distinct change in the avifauna.  As 2018 is the National Geographic Year of the Bird, our guests are getting in the spirit with plenty of birdwatching sessions from the aft deck during our sea days. Why not get involved and check out the Year of the Bird website (www.nationalgeographic.org/projects/year-of-the-bird) or follow #YearoftheBird and #BirdYourWorld on Twitter and Instagram. Lindblad is supporting this initiative by having YoB Ambassadors on our expeditions.
