  Duck. 
  

  

  This 
  duck 
  is 
  among 
  the 
  species 
  that 
  range 
  most 
  widely 
  in 
  the 
  Western 
  Hemi- 
  

   sphere. 
  It 
  is 
  strange 
  that 
  it 
  should 
  not 
  have 
  been 
  detected 
  in 
  Florida, 
  for 
  it 
  occurs 
  

   throughout 
  the 
  Bahamas, 
  even 
  in 
  the 
  most 
  northern 
  islands. 
  Thence 
  it 
  ranges 
  

   through 
  the 
  Greater 
  and 
  the 
  Lesser 
  Antilles 
  to 
  South 
  America. 
  In 
  Brazil 
  it 
  is 
  one 
  

   of 
  the 
  most 
  abundant 
  ducks 
  and 
  occurs 
  in 
  decreasing 
  numbers 
  even 
  south 
  to 
  the 
  

   Falkland 
  Islands. 
  It 
  has 
  been 
  recorded 
  from 
  every 
  country 
  of 
  South 
  America 
  except 
  

   Colombia, 
  Venezuela, 
  and 
  Ecuador. 
  It 
  breeds 
  throughout 
  its 
  range 
  from 
  the 
  Baha- 
  

   mas 
  to 
  the 
  Falklands.]

  Breeding 
  range. 
  — 
  The 
  wood 
  duck 
  is 
  more 
  closely 
  confined 
  to 
  the 
  

   United 
  States 
  than 
  any 
  other 
  North 
  American 
  duck. 
  South 
  of 
  this 
  

   country 
  it 
  is 
  not 
  a 
  rare 
  resident 
  in 
  Cuba 
  and 
  is 
  accidental 
  in 
  Jamaica 
  

   and 
  the 
  Bermudas. 
  It 
  occurs 
  in 
  California 
  south 
  to 
  Los 
  Angeles 
  and 
  

   Ventura 
  counties, 
  in 
  the 
  latter 
  of 
  which 
  it 
  breeds. 
  There 
  is 
  a 
  single 
  

   record 
  for 
  Mexico, 
  at 
  Mazatlan. 
  It 
  breeds 
  in 
  eastern 
  Texas, 
  south 
  

   rarely 
  to 
  San 
  Antonio; 
  thence 
  to 
  the 
  Pacific 
  slope 
  and 
  north 
  through- 
  

   out 
  the 
  whole 
  Rocky 
  Mountain 
  region 
  it 
  is 
  rare 
  or 
  accidental. 
  It 
  is 
  

   recorded 
  as 
  breeding 
  in 
  southwestern 
  Colorado 
  (Fort* 
  Lewis), 
  north- 
  

   ern 
  Idaho 
  (Fort 
  Sherman), 
  northern 
  Montana 
  (Flathead 
  Lake), 
  and 
  

   as 
  a 
  rare 
  migrant 
  in 
  various 
  localities 
  south 
  to 
  New 
  Mexico 
  and 
  

   Arizona. 
  

  

  The 
  northern 
  extension 
  of 
  its 
  range 
  is 
  found 
  in 
  Nova 
  Scotia 
  and 
  

   New 
  Brunswick, 
  for 
  the 
  species 
  is 
  not 
  yet 
  recorded 
  from 
  Newfound- 
  

   land, 
  and 
  there 
  seems 
  to 
  be 
  no 
  reliable 
  record 
  for 
  Labrador. 
  It 
  

   ranges 
  at 
  least 
  as 
  far 
  north 
  as 
  Montreal, 
  Ottawa, 
  Moose 
  Factory, 
  

   Trout 
  Lake, 
  and 
  Cumberland 
  House. 
  It 
  appears 
  to 
  be 
  absent 
  from 
  

   the 
  Rocky 
  Mountain 
  region 
  of 
  Canada, 
  but 
  occurs 
  in 
  southern 
  British 
  

   Columbia 
  (Agassiz, 
  Sumas, 
  Chilliwack, 
  and 
  Burnaby 
  Lake). 
  

  

  It 
  is 
  one 
  of 
  the 
  earliest 
  ducks 
  to 
  breed, 
  as 
  young 
  were 
  found 
  in 
  

   northern 
  Florida 
  on 
  March 
  19, 
  1877.
