﻿BIRDS 
  OF 
  NEW 
  YORK 
  87 
  

  

  to 
  birds 
  which 
  can 
  only 
  be 
  seen 
  in 
  particular 
  localities; 
  and 
  irregular, 
  indicat- 
  

   ing 
  that 
  the 
  species 
  may 
  be 
  much 
  more 
  common 
  in 
  some 
  seasons 
  than 
  in 
  

   others. 
  It 
  is 
  sometimes 
  necessary 
  to 
  rank 
  a 
  species 
  under 
  two, 
  or 
  even 
  

   three 
  heads, 
  as 
  for 
  instance 
  the 
  Junco 
  or 
  Common 
  snow 
  bird, 
  which 
  is 
  an 
  

   abundant 
  transient 
  visitant 
  in 
  Ontario 
  county, 
  an 
  uncommon 
  winter 
  visitant, 
  

   and 
  a 
  rare 
  summer 
  resident. 
  

  

  Migration 
  dates 
  given 
  in 
  the 
  third 
  column 
  represent 
  as 
  far 
  as 
  accessible 
  

   the 
  earliest, 
  average 
  and 
  fairly 
  late 
  dates 
  of 
  arrival 
  of 
  all 
  migratory 
  birds 
  

   from 
  the 
  south 
  and 
  in 
  the 
  fourth 
  column 
  is 
  recorded 
  the 
  date 
  of 
  departure 
  for 
  

   the 
  north 
  of 
  all 
  those 
  species 
  which 
  are 
  transient 
  or 
  winter 
  visitants. 
  The 
  

   fifth 
  column 
  contains 
  the 
  dates 
  at 
  which 
  these 
  species 
  return 
  from 
  the 
  north 
  

   again; 
  and 
  the 
  sixth 
  column 
  records 
  the 
  dates 
  of 
  departure 
  for 
  the 
  south 
  

   of 
  transients 
  and 
  summer 
  residents; 
  and 
  the 
  last 
  column 
  for 
  each 
  county 
  

   indicates 
  whether 
  the 
  species 
  breeds 
  within 
  its 
  borders 
  and, 
  where 
  possible, 
  

   gives 
  the 
  date 
  when 
  fresh 
  eggs 
  have 
  been 
  found. 
  

  

  Whenever 
  dates 
  are 
  given 
  in 
  these 
  columns 
  the 
  effort 
  has 
  been 
  made 
  

   to 
  record 
  the 
  earliest, 
  average, 
  and 
  late 
  dates 
  for 
  both 
  migration 
  and 
  nest- 
  

   ing, 
  but 
  unfortunately, 
  in 
  spite 
  of 
  the 
  unlimited 
  time 
  which 
  has 
  been 
  

   expended 
  with 
  this 
  object 
  in 
  view, 
  the 
  result 
  in 
  most 
  counties 
  has 
  been 
  far 
  

   from 
  satisfactory, 
  yet 
  represents 
  the 
  best 
  that 
  can 
  be 
  done 
  at 
  the 
  present 
  

   time. 
  In 
  nearly 
  every 
  county 
  it 
  would 
  be 
  possible 
  to 
  insert 
  more 
  complete 
  

   and 
  accurate 
  dates, 
  both 
  for 
  migration 
  and 
  nesting, 
  than 
  those 
  which 
  

   appear, 
  from 
  our 
  knowledge 
  of 
  what 
  must 
  be 
  true 
  in 
  those 
  localities; 
  we 
  

   have 
  considered 
  it 
  far 
  better, 
  however, 
  to 
  adhere 
  to 
  the 
  actual 
  date 
  received 
  

   and 
  refer 
  those 
  who 
  are 
  in 
  search 
  of 
  fuller 
  dates 
  of 
  migration 
  in 
  different 
  

   parts 
  of 
  the 
  State, 
  to 
  the 
  schedules 
  for 
  Cayuga, 
  Erie, 
  Lewis, 
  Madison, 
  

   Monroe, 
  Ontario, 
  Orange, 
  Saratoga, 
  Steuben, 
  Suffolk, 
  Tompkins, 
  West- 
  

   chester 
  and 
  Yates, 
  where 
  the 
  dates 
  are 
  based 
  on 
  observations 
  extending 
  

   through 
  a 
  series 
  of 
  years. 
  In 
  cases 
  of 
  rare 
  or 
  accidental 
  birds 
  with 
  only 
  

   one 
  or 
  two 
  dates 
  for 
  the 
  county, 
  we 
  have 
  entered 
  the 
  date 
  in 
  the 
  column 
  

   where 
  it 
  seemed 
  most 
  appropriate 
  and 
  have 
  often 
  inserted 
  the 
  year, 
  thereby 
  

   making 
  the 
  record 
  of 
  greater 
  value.
