  until 
  

   quite

  Breeding 
  range. 
  — 
  The 
  summer 
  home 
  of 
  this 
  species 
  seems 
  to 
  com- 
  

   prise 
  two 
  general 
  areas 
  separated 
  by 
  the 
  Rocky 
  Mountains. 
  The 
  

   greater 
  number 
  breed 
  in 
  the 
  interior, 
  from 
  North 
  Dakota 
  and 
  Minne- 
  

   sota 
  north 
  to 
  Athabasca 
  Lake 
  and 
  east 
  to 
  the 
  western 
  side 
  of 
  Lake 
  

   Winnipeg. 
  It 
  breeds 
  rarely 
  south 
  to 
  southern 
  Minnesota 
  (Minneapo- 
  

   lis,

  Though

  the 
  

   species 
  may 
  be 
  found 
  breeding 
  in

  The

  is 
  the 
  prin- 
  

   cipal 
  winter 
  home 
  of 
  the 
  ring-necked 
  duck, 
  and 
  here 
  locally 
  it 
  is 
  the 
  

   most 
  abundant 
  duck 
  at 
  this 
  season. 
  It 
  is 
  common 
  also 
  in 
  the 
  Bahamas 
  

   and 
  Cuba, 
  rare 
  in

  and 
  has 
  been 
  noted

  Rico, 
  and 
  

   once 
  in
