    Puffins seem most at home when they're at sea. Their final winter destination is in waters over epic “coral canyons” that go deeper than the Grand Canyon, and huge submerged mountain ranges that stretch for hundreds of miles along the ocean floor, according to the National Audubon Society's website. The zone is known for its rich biodiversity and offers an abundant food supply for puffins.

    Stephen Cress, founder of the Puffin Project, has spent more than 40 summers studying puffins off the coast of Maine, but he never knew where the puffins went in the winter. Now, thanks to GPS tracking, he knows the answer.
