The Auks! A family made up of the murres, puffins, murrelets, guillemots and auklets. Basically the Penguins of thh Northern Hemisphere. These cute

 little seabirds live in some pretty extreme environments out in the ocean and on far off cliffsides and islands. They can be very secretive and hard to observe.

 In fact the Marbled Murrelet was so sneaky that it's nest was the last one descried of all North American birds.
