  the

   feathers, 
  yellow 
  or 
  yellowish

  on 
  the

  of 
  the

  and 
  particularly 
  

   by 
  the 
  different 
  shape 
  and

  of 
  the 
  bill, 
  as 
  shown 
  by

  The 
  sternum 
  is 
  hollowed 
  out 
  to 
  receive 
  

   a 
  long 
  fold 
  of 
  the 
  trachea, 
  which 
  is 
  more 
  convoluted 
  in

   foraiing 
  a

  The 
  Whistling 
  swan, 
  or 
  American 
  swan, 
  breeds 
  in 
  the 
  arctic 
  regions 
  

   and 
  appears 
  in 
  New 
  York 
  as 
  a 
  spring 
  and 
  fall 
  migrant 
  both 
  on 
  the 
  coast 
  

   and 
  on 
  the 
  interior 
  lakes. 
  It 
  is 
  more 
  common 
  in 
  western 
  New 
  York 
  than 
  

   on 
  the 
  coast 
  and 
  may 
  be 
  regarded 
  as 
  a 
  regular 
  migrant, 
  appearing 
  in 
  spring
