  The 
  sequence 
  of 
  species 
  is 
  nearh' 
  the 
  same 
  each 
  season. 
  The 
  Bhie- 
  

   bird, 
  Robin, 
  Song 
  sparrow 
  and 
  Redwing 
  are 
  among 
  the 
  earliest 
  arrivals. 
  

   Late 
  in 
  March, 
  or 
  early 
  in 
  April, 
  the 
  Phoebe, 
  Kingfisher, 
  Purple 
  finch 
  and 
  

   Vesper 
  sparrow; 
  by 
  the 
  third 
  week 
  in 
  April, 
  the 
  Martin, 
  Barn 
  swallow 
  

   and 
  Spotted 
  sandpiper 
  are 
  probably 
  here. 
  Early 
  in 
  May 
  comes 
  the 
  great 
  

   wave 
  bringing 
  the 
  Oriole, 
  Bobolink, 
  Catbird, 
  Kingbird 
  and 
  all 
  the 
  warblers, 
  

   flycatchers 
  and 
  vireos, 
  the 
  latest 
  among 
  which 
  will 
  probably 
  be 
  the 
  Wood 
  

   pewee 
  and 
  the 
  Mourning 
  and 
  Black-poll 
  warblers. 
  The 
  males 
  of 
  each 
  species 
  

   usually 
  precede 
  the 
  females 
  by 
  several 
  da^'s, 
  as 
  is 
  noticeable 
  in 
  the 
  case 
  

   of 
  the 
  Oriole, 
  vSapsucker, 
  Bobolink 
  and 
  Red-winged 
  blackbird. 
  Some 
  have 
  

   supposed 
  that 
  the 
  first 
  individuals 
  of 
  each 
  species 
  to 
  arrive 
  are 
  those 
  which 
  

   are 
  destined 
  to 
  travel 
  farthest 
  north. 
  This 
  may 
  be 
  true 
  in 
  the 
  case 
  of 
  some 
  

   species, 
  but 
  in 
  most 
  cases 
  the 
  first 
  to 
  arrive 
  are 
  the 
  individuals 
  whose 
  home 
  

   is 
  at 
  the 
  station, 
  while 
  the 
  last 
  of 
  all 
  to 
  arrive 
  are 
  those 
  going 
  farthest 
  

   north. 
  In 
  the 
  vicinity 
  of 
  Rochester 
  it 
  is 
  a 
  common 
  thing 
  to 
  see 
  robins, 
  

   Blue 
  jays 
  and 
  Red-tailed 
  hawks 
  migrating 
  along 
  the 
  shores 
  of 
  Lake 
  Ontario, 
  

   evidently 
  en 
  route 
  for 
  the 
  far 
  north 
  at 
  a 
  time 
  when 
  individuals 
  of 
  the 
  same 
  

   species 
  at 
  Rochester 
  have 
  nests 
  and 
  eggs 
  and 
  sometimes 
  young. 
  

  

  During 
  migration 
  birds 
  follow, 
  to 
  some 
  extent, 
  the 
  seashore, 
  lake 
  shore 
  

   and 
  river 
  valleys, 
  as 
  natural 
  highways 
  of 
  travel. 
  The 
  principal 
  routes 
  across 
  

   New 
  York 
  State 
  are 
  along 
  the 
  coast, 
  and 
  up 
  the 
  Hudson-Champlain 
  valley, 
  

   and 
  along 
  the 
  shores 
  of 
  Lake 
  Erie 
  and 
  Lake 
  Ontario. 
  Lesser 
  ones 
  enter 
  

   the 
  State 
  up 
  the 
  Delaware, 
  Susquehanna 
  and 
  Alleghany 
  valleys. 
  

   These 
  routes 
  are 
  based 
  chiefly 
  on 
  three 
  classes 
  of 
  observations. 
  The 
  

   most 
  obvious 
  of 
  these 
  is 
  the 
  direction 
  taken 
  b\' 
  da}' 
  migrants 
  which 
  are 
  

   seen 
  to 
  pass 
  in 
  considerable 
  numbers 
  over 
  the 
  country 
  in 
  the 
  courses 
  indi- 
  

   cated. 
  The 
  writer 
  has 
  frequently 
  seen 
  dozens 
  of 
  hawks, 
  hundreds 
  of 
  

   swallows, 
  and 
  thousands 
  of 
  blackbirds 
  during 
  the 
  spring 
  inigration 
  passing 
  

   along 
  the 
  southern 
  shore 
  of 
  Lake 
  Ontario 
  in 
  the 
  course 
  of 
  a 
  single 
  hour, 
  

   all 
  traveling 
  toward 
  the 
  east. 
  Ducks 
  and 
  blackbirds 
  are 
  especially 
  prone 
  to 
  

   follow 
  the 
  river 
  courses 
  and 
  their 
  movements 
  point 
  out 
  the 
  passage 
  from 
  

   one 
  valley 
  to 
  the 
  next. 
  Great 
  caution 
  must 
  be 
  used, 
  however, 
  not 
  to 
  confuse
