After lunch, we had another landing at Danco Island, named after the Polish geologist who died during Gerlache’s Belgian Expedition of 1898–99. After coming ashore, we walked up to a rookery filled with molting penguins—adults and chicks. The adults had a dark bronze-black coloration of old feathers, while the chicks had fresh jet-black feathers, with some still showing remnants of their down poking through. Many brave guests also took the polar plunge at the beach on Danco Island.
