  but 
  ground-color 
  of

  brownish 
  gray, 
  with

  and 
  upper

  A 
  single 
  specimen 
  of 
  this 
  bird 
  was 
  taken 
  on 
  Long 
  Island, 
  May

  1833,

  is 
  now 
  in

   sonian 
  Collection,

  As 
  no 
  further 
  specimens

  appeared, 
  it 
  is 
  

   believed

  be 
  a 
  hybrid, 
  or 
  abnormal 
  example 
  of

  maculata.

  The 
  Baird 
  sandpiper 
  is 
  a 
  fairly 
  common 
  transient 
  on 
  the 
  shores 
  of 
  the 
  

   Great 
  Lakes 
  and 
  the 
  central 
  chain, 
  and 
  is 
  not 
  rare 
  on 
  Long 
  Island. 
  It 
  is 
  

   a 
  nearctic 
  species, 
  breeding 
  in 
  the 
  arctic 
  region 
  and 
  migrating 
  through 
  the 
  

   interior 
  of 
  North 
  America 
  to 
  Chili 
  and 
  Patagonia. 
  It 
  was 
  overlooked 
  by 
  

   the 
  early 
  ornithologists, 
  and 
  can 
  be 
  recognized 
  with 
  certainty 
  only 
  when 
  

   collected 
  and 
  carefully 
  examined.
