﻿BIRD 
  BANDING 
  — 
  LINCOLN

  every 
  bird 
  that 
  enters 
  a 
  chimney 
  to 
  roost 
  for 
  the 
  night. 
  Most 
  of 
  

   these 
  have 
  been 
  taken 
  in 
  the 
  vicinity 
  of 
  Thomasville, 
  Ga., 
  and 
  

   Tallahassee, 
  Fla., 
  ahd 
  through 
  the 
  continued 
  operation 
  of 
  the 
  traps, 
  

   twice 
  each 
  year, 
  many 
  return 
  records 
  are 
  being 
  obtained. 
  Several 
  

   swifts 
  have 
  been 
  recaptured 
  at 
  the 
  banding 
  points 
  in 
  both 
  spring 
  

   and 
  fall, 
  showing 
  that 
  the 
  route 
  for 
  the 
  individual 
  birds 
  is 
  ap- 
  

   parently 
  the 
  same 
  for 
  both 
  migrations. 
  Birds 
  also 
  have 
  been 
  taken 
  

   from 
  a 
  chimney 
  in 
  one 
  town, 
  and 
  a 
  week 
  or 
  ten 
  days 
  later 
  recaptured 
  

   at 
  another 
  15 
  to 
  30 
  miles 
  distant. 
  Swifts 
  banded 
  at 
  these 
  points 
  

   have 
  been 
  recovered 
  north 
  through 
  Pennsylvania 
  and 
  New 
  York 
  to 
  

   New 
  Brunswick 
  and 
  Nova 
  Scotia. 
  

  

  Crows 
  and 
  jays. 
  — 
  The 
  migration 
  flights 
  of 
  the 
  Corvidm 
  are 
  not 
  well 
  

   understood, 
  due 
  principally 
  to 
  the 
  fact 
  that 
  the 
  different 
  species 
  are 
  

   frequently 
  observed 
  continuously 
  throughout 
  the 
  year 
  in 
  many 
  lo- 
  

   calities. 
  Their 
  journeys 
  are, 
  however, 
  more 
  or 
  less 
  regular, 
  banding 
  

   returns 
  showing 
  some 
  interesting 
  and 
  lengthy 
  flights. 
  Blue 
  jays 
  

   {Gyanocitta 
  aetata) 
  banded 
  in 
  Illinois 
  and 
  Iowa 
  (pi. 
  9, 
  fig. 
  1) 
  have 
  

   been 
  retaken 
  in 
  Missouri 
  and 
  Arkansas; 
  and 
  a 
  magpie 
  {Pica 
  p. 
  hud- 
  

   sonia), 
  banded 
  near 
  Laramie, 
  Wyo., 
  in 
  May, 
  was 
  killed 
  near 
  Rosita, 
  

   Colo., 
  during 
  the 
  following 
  January. 
  The 
  crow 
  {Corvus 
  l)raGhy- 
  

   rhynchos) 
  appears 
  to 
  make 
  the 
  longest 
  flights 
  of 
  any 
  member 
  of 
  this 
  

   family. 
  Birds 
  banded 
  in 
  Illinois 
  have 
  been 
  retaken 
  in 
  Wisconsin 
  

   and 
  Michigan; 
  one 
  banded 
  in 
  Saskatchewan 
  in 
  June 
  was 
  killed 
  in 
  

   Oklahoma 
  in 
  the 
  succeeding 
  January, 
  while 
  one 
  banded 
  in 
  Oklahoma 
  

   in 
  January 
  was 
  recovered 
  three 
  months 
  later 
  in 
  Minnesota. 
  

  

  Blackbirds. 
  — 
  In 
  this 
  family 
  there 
  are 
  two 
  species 
  for 
  which 
  return 
  

   data 
  are 
  rapidly 
  accumulating, 
  due 
  to 
  the 
  large 
  numbers 
  that 
  are 
  be- 
  

   ing 
  marked. 
  Because 
  of 
  their 
  local 
  economic 
  importance, 
  it 
  is 
  ex- 
  

   pected 
  that 
  information 
  from 
  recovered 
  birds 
  will 
  be 
  useful 
  in 
  the 
  

   formulation 
  of 
  adequate 
  control 
  measures. 
  

  

  The 
  total 
  number 
  of 
  banded 
  red-winged 
  blackbirds 
  {Agelaivs 
  

   phosniceiis) 
  is 
  only 
  slightly 
  more 
  than 
  3,000, 
  but, 
  nevertheless, 
  

   many 
  interesting 
  returns 
  have 
  been 
  obtained. 
  Many 
  gaps 
  remain 
  

   to 
  be 
  filled 
  in, 
  but 
  the 
  data 
  at 
  hand 
  indicate 
  the 
  route 
  followed 
  by 
  

   these 
  birds, 
  from 
  Connecticut 
  through 
  New 
  Jersey 
  and 
  Maryland; 
  

   from 
  Michigan, 
  Minnesota, 
  and 
  Wisconsin 
  south 
  through 
  Illinois 
  

   and 
  Tennessee 
  to 
  Alabama 
  and 
  Texas. 
  

  

  The 
  grackles 
  {Quiscalus 
  quiscula) 
  come 
  so 
  readily 
  into 
  yards 
  and 
  

   gardens 
  that 
  it 
  is 
  not 
  surprising 
  that 
  more 
  than 
  7,000 
  have 
  been 
  

   marked 
  by 
  station 
  operators. 
  From 
  these 
  the 
  returns 
  exceed 
  350. 
  

   They 
  can, 
  of 
  course, 
  be 
  only 
  briefly 
  mentioned 
  in 
  this 
  paper, 
  but 
  it 
  is 
  

   apparent 
  that 
  eventually 
  these 
  data 
  will 
  be 
  sufficiently 
  numerous 
  

   to 
  form 
  the 
  basis 
  of 
  an 
  independent 
  contribution.
