  distinct 
  C. 
  auratus 
  and 
  C 
  mexicanus, 
  which 
  Baird 
  in 
  1858 
  called. 
  

   C. 
  hybridus. 
  Formerly 
  only 
  known 
  from 
  the 
  Upper 
  Missouri 
  

   and 
  Yellowstone 
  districts, 
  these 
  " 
  hybrid 
  Flickers 
  " 
  are 
  now 
  

   ascertained 
  to 
  extend 
  in 
  a 
  broad 
  belt 
  all 
  across 
  the 
  continent, 
  

   from 
  British 
  Columbia 
  to 
  the 
  Gulf 
  of 
  Mexico, 
  as 
  shown 
  in 
  Mr. 
  

   Allen's 
  excellent 
  maps, 
  separating 
  the 
  area 
  of 
  C. 
  auratus 
  on 
  the 
  

   north-east 
  from 
  that 
  of 
  C. 
  mexicanus 
  on 
  the 
  south-west. 
  They 
  

   present 
  " 
  ever 
  varying 
  combinations 
  of 
  the 
  characters 
  of 
  the 
  

   two 
  birds/'' 
  from 
  individuals 
  of 
  C. 
  auratus 
  that 
  show 
  only 
  the 
  

   slightest 
  traces 
  of 
  C. 
  mexicanus, 
  or 
  conversely 
  individuals 
  

   of 
  C. 
  mexicanus 
  with 
  very 
  slight 
  traces 
  of 
  C. 
  auratus, 
  to 
  

   examples 
  in 
  which 
  the 
  characters 
  of 
  the 
  two 
  species 
  are 
  

   almost 
  equally 
  blended. 
  After 
  a 
  full 
  discussion 
  of 
  the 
  facts, 
  

   the 
  author's 
  conclusion 
  is 
  that 
  his 
  investigations 
  ''tend 
  

   strongly 
  to 
  confirm 
  Baird's 
  startling 
  hypothesis 
  of 
  hybridi- 
  

   zation 
  on 
  a 
  grand 
  scale"" 
  between 
  these 
  two 
  species. 
  " 
  None 
  

   of 
  the 
  other 
  hypotheses 
  so 
  far 
  advanced 
  so 
  fully, 
  or 
  in 
  fact 
  to 
  

   any 
  great 
  extent, 
  meet 
  the 
  requirements 
  of 
  the 
  case.''
