The Emperor penguins are incredible creatures, trekking many miles to the waters edge of the sea ice to forage. In this series of three photos they are returning to the colony to feed their awaiting chicks. The Emperors use different techniques to move forward. They walk and when they get tired of walking they fall over on their bellies to toboggan. Tobogganing is faster but they have to be careful not to wear out their belly feathers. We visited in the polar summer and still the ice edge was a solid 6 miles away. I can’t begin to understand how they manage to do this in winter time, when they have to trek for 60 to 70 miles!
