Far from sight of land, a stiff wind greeted us this morning, along with a surprising array of winged land animals that were blown out to sea: hundreds of moths and at least seven birds took refuge on our ship. We spent the day at sea, sailing south and west across the broad Bahia Blanca. We encountered our first penguins of the voyage (Magellanic penguins), and we had some interesting albeit fleeting marine mammal encounters (southern right whale, humpback whale, blue whale, common dolphin, and South American sea lion).
