Happy World Penguin Day!

Did you know that unlike most birds—which lose and replace a few feathers at a time—penguins molt all at once, spending two or three weeks land-bound as they undergo what is called the catastrophic molt?

And that fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs?

More fun facts found here. Animation from the TED-Ed lesson The popularity, plight and poop of penguins – Dyan deNapoli
