Order PYGOPODES. Diving Birds 



The Pygopodes (Gr., rump, foot) are characterized by 

 the fact that the legs enter the body at the extreme end, at 

 or near the rump, a physical construction that gives them 

 great powers of swimming and diving but makes them almost 

 helpless when on land. With the exception of the Puffin,

 breasts. Their plumage is very thick and is completely 

 waterproof.
