 lilac. The head and throat are black, whilst on each 

 side of the neck is a patch of vivid orange feathers. 

 The rest of the body is marked in the same way as

 Dr. Herbert Klugh has calculated that the Emperor 

 penguin lives for thirty-five years. 



Evidence goes to show that the young birds
