Penguins share parenting responsibilities 50-50– one parent watches the nest, one parent gets to go feed, and then they switch. Over and over and over.
Well some of these damn rookeries were WAY far away from the water! HUGE journeys for little foot-tall penguins, especially when they can only waddle on land, especially when the snow is up over their heads!
How do they make that journey just a little bit easier?
Same way we make long journeys on land a little easier– HIGHWAYS!
