  Breeding 
  range. 
  — 
  The 
  principal 
  summer 
  home 
  of 
  this 
  eider 
  is 
  on 
  the 
  

   coasts 
  and 
  islands 
  of 
  Bering 
  Sea 
  and 
  along 
  the 
  coast 
  of 
  the 
  Arctic 
  

   Ocean 
  between 
  the 
  mouths 
  of 
  the 
  Mackenzie 
  and 
  the 
  Coppermine 
  

   rivers. 
  The 
  species 
  breeds 
  west 
  to 
  the 
  northeastern 
  coast 
  of 
  Siberia 
  

   and 
  south 
  to 
  Cook 
  Inlet, 
  Kadiak 
  Island, 
  the 
  Aleutians, 
  Near,

  it

  accidental 
  in 
  the 
  interior 
  at 
  Great 
  Slave 
  Lake 
  

   and 
  at 
  Lawrence,

  It 
  is 
  probable 
  that 
  the 
  eiders 
  so 
  abundant 
  

   on 
  Banks

  belong 
  to

  Earty

  the 
  last 
  of 
  April, 
  but 
  usually 
  they

  about 
  

   May

  At 
  Point

  the 
  dates 
  of 
  arrival 
  are

  and

   their

  the

   of

  Many 
  individuals 
  winter 
  and 
  summer 
  in 
  the

   while 
  the 
  birds 
  breeding 
  about 
  the

   migrate 
  at
