  tendenc}^ 
  to 
  grayish 
  rather 
  than 
  rufous 
  on 
  the 
  upper

  the 
  

   tail 
  is 
  usually 
  gray. 
  Birds 
  from 
  the 
  Adirondacks 
  are 
  nearly 
  typical 
  of 
  

   this 
  subspecies.

  As 
  stated 
  under 
  the 
  common 
  Ruffed 
  grouse, 
  the 
  birds 
  from 
  a 
  large 
  

   portion 
  of 
  New 
  York 
  State 
  are 
  intermediate 
  between 
  this 
  subspecies 
  and 
  the 
  

   preceding. 
  It 
  is 
  practically 
  impossible 
  to 
  assign 
  many 
  New 
  York 
  specimens 
  

   to 
  one 
  subspecies 
  or 
  the 
  other. 
  The 
  illustration 
  on 
  page 
  372, 
  of 
  typical 
  

   New 
  York 
  birds 
  will 
  show 
  the 
  degree 
  of 
  darkness 
  in 
  the 
  barring 
  of 
  the 
  under 
  

   parts, 
  which 
  is 
  the 
  most 
  tangible 
  means 
  of 
  distinction 
  between 
  them. 
  

   The 
  two 
  varieties 
  are 
  identical 
  in 
  habits 
  and 
  their 
  eggs 
  indistinguishable.
