The Amphibious Bird  Source: Wikipedia  Atlantic Puffins truly
are remarkable birds. Puffins can swim underwater and fly in the
air. They have evolved their high speed wings and their rudder
like webbed feet enabling them to swim efficiently underwater,
where they catch small fish including herring and sand eel. They
can dive to a depth of 200 ft and can stay underwater for 20 to
30 seconds. When underwater, the puffin is essentially flying,
but it just has more resistance than in the air.  How exactly
does a Puffin manage to dive and swim through the water so
effectively? Well, the Puffin partly folds its wings and has its
hand wings directed backwards. Because of this and its ability
to flap very fast, during the downstroke the bird accelerates
upwards and forward through the water. Then, during the
upstroke, the bird accelerates downwards and rarely also
forwards. Most of the time however, the upstroke just causes the
puffin to decelerate.  Although they do not have the capacity to
breath underwater for as
