There are two types of puffins found in Glacier Bay: tufted and horned. Pictured here is the rarer horned puffin, recognizable for its white belly, black wings, colorful bill, and most notably, a “horn” near the eye which is actually a feather. These birds are sometimes seen in mixed groups with their more common cousins, the tufted puffins. Horned puffins are known to nest on South Marble Island and in Tarr Inlet. Puffins are members of the Alcid family of birds which are stout, compact birds that dive deep to feed upon small schooling fish. Their dense bones and heavy bodies make them excellent swimmers, but not the most graceful of flyers. Photographer: Sean Neilson
