Monday is World Penguin Day!
Actually, it’s one of two days dedicated to the adorable, waddling birds. April 25 is World Penguin Day while January 20th is Penguin Awareness Day.
In addition to two penguin days, there are believed to be 17 penguin species, ranging from the Little Blue Penguin to the mighty Emperor Penguin. And several of these are threatened by climate change.
In honor of everyone’s favorite tuxedo-ed bird, National Geographic presents some of the best penguin photos taken by award-winning photographer Paul Nicklen.
