Penguins are some of the most adorable, lovable and impressive creatures in the animal kingdom, so why not dedicate a day to these flightless birds?
World Penguin Day is a celebratory and educative initiative that encourages people to learn more about penguins and their environment, how important they are to our ecosystems and the threats they face. Interested in learning more about this day? Then let’s dive in!
The particulars of penguins
These distinctive black and white birds are highly adapted to aquatic life, their wings have evolved into flippers and their excellent swimming abilities allowing most species to dive around 200m deep, with emperor penguins even reaching depths of 500m! They’re camouflaged to protect against predators from above and below, and their glossy feathers trap air to both keep them warm and help them stay afloat.

Penguins vary quite significantly in size, from the large emperor penguin, reaching heights of over 1m, to the little blue penguin, coming in at just over 30cm tall. In ancient times there were even giant species of penguin that grew almost 2m high and weighed 80kg!
Found all over the Southern Hemisphere, from Antarctica to the Galápagos Islands, penguins are famous for their endearing waddles, their dedicated chick hatching efforts and, for those based in icy climates, their trick of huddling to stay warm. They’re even known to enjoy a spot of tobogganing, gliding on their bellies over the ice!
History of World Penguin Day
World Penguin Day takes place during the annual northern migration of Adélie penguins, a species of penguin that is native to Antarctica. Adélie penguins migrate north to have better access to food during the winter months when the sea ice expands and then, during the summer, return to the coastal beaches of Antarctica to build their nests.
This annual celebration of penguins was created at McMurdo Station, an American research center on Ross Island. Researchers noticed that the Adélie penguins began their migration around this day each year, and so they founded World Penguin Day as a way to mark the occasion and raise awareness of these creatures.
While the day originated from the Adélie penguin’s migration habits, it celebrates all species of penguin and highlights the plight of these water-loving creatures. Of the 17 or so species around today (the total number of species varies depending on how you classify them, but there are at least 17 and possibly as many as 20!), sadly 10 of them have been deemed endangered or vulnerable by the International Union for Conservation of Nature (IUCN) and 3 are considered near threatened.
Penguins spend up to three quarters of their lives out at sea and are reliant on the oceans for food. Overfishing and pollution such as plastic and oil spills therefore pose a real threat to these birds and have contributed to decreasing populations, which in turn has a knock-on effect on the wider ecosystem. And for those species based in the Antarctic (the emperor penguin and the Adélie penguin), climate change is shrinking the sea ice, which not only impinges on their habitat but can also impact chick hatching times and the availability of food.
