  Thus 
  far, 
  banded 
  marsh 
  hawks 
  {Circus 
  Jmdsonius) 
  have 
  yielded 
  

   the 
  largest 
  number 
  of 
  interesting 
  returns. 
  Birds 
  banded 
  north 
  as 
  

   far 
  as 
  Ontario 
  have 
  been 
  recovered 
  in 
  North 
  Carolina 
  and 
  Florida; 
  

   and 
  birds 
  banded 
  in 
  central 
  Illinois 
  have 
  been 
  reported 
  from 
  Texas 
  

   and 
  also 
  from 
  Michigan. 
  A 
  Cooper's 
  hawk 
  {Accipiter 
  cooperi) 
  

   banded 
  at 
  Willoughby, 
  Ohio, 
  was 
  killed 
  during 
  the 
  winter 
  of 
  the 
  

   same 
  year 
  at 
  Sublime, 
  Tex. 
  ; 
  and 
  a 
  ferruginous 
  rough-leg 
  {ArcMbuteo 
  

   ferrugineus) 
  banded 
  at 
  Red 
  Deer 
  River, 
  Alberta, 
  was 
  taken 
  about 
  

   three 
  months 
  later, 
  at 
  Kimball, 
  Nebr. 
  Two 
  young 
  duck 
  hawks 
  

   {Falco 
  p. 
  afiatum), 
  banded 
  on 
  the 
  same 
  day 
  at 
  Russell, 
  Mass., 
  were 
  

   both 
  killed 
  during 
  the 
  following 
  spring, 
  one 
  at 
  Canton, 
  Pa., 
  and 
  the 
  

   other 
  at 
  Nokesville, 
  Va. 
  Another 
  bird 
  of 
  this 
  species, 
  banded 
  at 
  

   Kings 
  Point, 
  Yukon, 
  in 
  July, 
  1924, 
  was 
  taken 
  at 
  Duchesne, 
  Utah, 
  

   duting 
  the 
  following 
  February, 
  about 
  2,300 
  miles 
  from 
  the 
  point 
  of 
  

   banding. 
  

  

  Some 
  interesting 
  light 
  has 
  been 
  shed 
  on 
  the 
  movements 
  of 
  some 
  of 
  

   the 
  owls 
  (pi. 
  T, 
  fig. 
  1), 
  although 
  much 
  more 
  data 
  are 
  needed. 
  

  

  The 
  screech 
  owl 
  {Otus 
  asio) 
  seems 
  to 
  be 
  sedentary 
  throughout 
  its 
  

   range. 
  Returns 
  from 
  birds 
  banded 
  at 
  points 
  in 
  New 
  England, 
  

   through 
  the 
  plains, 
  and 
  Rocky 
  Mountain 
  areas 
  to 
  the 
  Pacific 
  coast, 
  

   all 
  are 
  in 
  the 
  same 
  general 
  vicinity 
  of 
  banding. 
  On 
  the 
  other 
  hand, 
  

   banded 
  barn 
  owls 
  {Tyto 
  pratincola) 
  have 
  yielded 
  a 
  few 
  returns 
  show- 
  

   ing 
  that 
  these 
  birds 
  can 
  and 
  do 
  perform 
  lengthy 
  journeys. 
  One 
  

   banded 
  at 
  Oradell, 
  N. 
  J., 
  in 
  summer, 
  was 
  taken 
  the 
  following 
  Janu- 
  

   ary, 
  at 
  Savannah, 
  Ga. 
  ; 
  another, 
  also 
  banded 
  in 
  New 
  Jersey, 
  was 
  re- 
  

   covered 
  at 
  Wilmington, 
  N. 
  C. 
  ; 
  while 
  a 
  third, 
  banded 
  at 
  Nashville, 
  

   Tenn., 
  was 
  killed 
  about 
  six 
  months 
  later, 
  at 
  Opp, 
  Ala. 
  

  

  An 
  interesting 
  record 
  also 
  is 
  at 
  hand 
  for 
  a 
  snowy 
  owl 
  {Nyctea 
  

   nyctea) 
  banded 
  early 
  in 
  July, 
  1924, 
  at 
  Hooper 
  Bay, 
  Alaska, 
  and 
  

   killed 
  in 
  November 
  of 
  the 
  following 
  year, 
  on 
  King 
  Island, 
  off 
  the 
  

   coast 
  in 
  Bering 
  Sea. 
  

  

  Chimney 
  swift. 
  — 
  Among 
  the 
  smaller 
  birds 
  the 
  migrations 
  of 
  the 
  

   chimney 
  swift 
  {Chcetura 
  pelagica) 
  (pi. 
  7, 
  fig. 
  2) 
  holds 
  an 
  unfailing 
  

   interest, 
  principally 
  because 
  of 
  the 
  lack 
  of 
  definite 
  information 
  re- 
  

   garding 
  its 
  winter 
  home. 
  The 
  innumerable 
  host 
  of 
  these 
  birds 
  that 
  

   gathers 
  in 
  the 
  Gulf 
  States, 
  disappears 
  suddenly 
  and 
  completely 
  in 
  

   the 
  fall, 
  causing 
  many 
  of 
  the 
  credulous 
  to 
  still 
  maintain 
  that 
  they 
  

   spend 
  the 
  winter 
  on 
  hibernation 
  beneath 
  the 
  waters 
  of 
  the 
  Gulf 
  of 
  

   Mexico. 
  

  

  Although 
  banding 
  was 
  not 
  considered 
  as 
  a 
  means 
  of 
  tracing 
  them 
  

   beyond 
  the 
  borders 
  of 
  the 
  United 
  States, 
  it 
  was 
  obvious 
  that 
  a 
  species 
  

   available 
  in 
  such 
  large 
  numbers 
  should 
  receive 
  attention. 
  During 
  

   the 
  last 
  few 
  years 
  more 
  than 
  11,000 
  have 
  been 
  captured 
  for 
  banding 
  

   by 
  means 
  of 
  specially 
  constructed 
  traps 
  (pi. 
  8) 
  that 
  literally 
  take
