Tuxedoed mariners

Cute, clumsy and completely captivating, penguins steal the show today. World Penguin Day is all about celebrating these flightless birds while raising awareness about their habitats. This day originated at McMurdo Station, an American research centre on Ross Island in Antarctica, where scientists observed Adélie penguins starting their yearly migration around this time. Inspired by this natural event, the observance was created to shed light on penguins' role in the ecosystem, the threats they face and the urgency of protecting their habitats.
