  (PI.

  !.)• 
  The 
  returns 
  received 
  are 
  siifRcienth^ 
  

   numerous 
  to 
  indicate 
  the 
  probability 
  in 
  the 
  near 
  future 
  of 
  an 
  inter- 
  

   esting 
  study 
  of 
  the 
  movements 
  of 
  this 
  attractive 
  bird. 
  Banded 
  in- 
  

   dividuals 
  have 
  been 
  recovered 
  south 
  through 
  the 
  valley 
  of 
  the 
  Mis- 
  

   sissippi 
  River 
  to 
  its 
  delta, 
  on 
  the 
  Atlantic 
  coast 
  south 
  of 
  Chesapeake 
  

   Bay 
  to 
  Key 
  West, 
  Fla., 
  and 
  in 
  four 
  cases 
  from 
  South 
  America 
  at 
  

   the 
  mouth 
  of 
  the 
  Mairdalena 
  River, 
  Colombia. 
  One 
  bird 
  was 
  re- 
  

   taken 
  in 
  central 
  Oklahoma 
  and 
  (in 
  the 
  succeeding 
  season) 
  three 
  

   others 
  were 
  found 
  in 
  Nova 
  Scotia. 
  A 
  small 
  colony 
  of 
  this 
  species 
  

   breeds 
  in 
  the 
  Gulf 
  of 
  St. 
  Lawrence, 
  and 
  it 
  is 
  assumed 
  that 
  the 
  

   banded 
  birds 
  recaptured 
  in 
  Nova 
  Scotia 
  had 
  moved 
  north 
  in 
  com- 
  

   pany 
  with 
  members 
  of 
  this 
  colony 
  rather 
  than 
  with 
  those 
  of 
  their 
  

   parent 
  colony 
  from 
  Lake 
  Michigan. 
  

  

  Commion 
  tern. 
  — 
  Breeding 
  colonies 
  of 
  the 
  graceful 
  common 
  tern 
  

   {Sterna, 
  hirimdo) 
  have 
  been 
  regularly 
  visited 
  by 
  banders, 
  the 
  gross 
  

   result 
  of 
  their 
  efforts 
  being 
  the 
  banding 
  of 
  more 
  than 
  20,000 
  birds. 
  

   The 
  number 
  of 
  returns 
  received 
  is, 
  however, 
  disproportionate, 
  due 
  

   probably 
  to 
  the 
  small 
  size 
  of 
  the 
  carriers 
  and 
  their 
  efficient 
  protec- 
  

   tion 
  under 
  the 
  terms 
  of 
  the 
  migratory 
  bird 
  treaty 
  act. 
  

  

  The 
  data 
  obtained 
  are 
  nevertheless 
  of 
  much 
  interest 
  and 
  are 
  gradu- 
  

   ally 
  building 
  up 
  a 
  chain 
  of 
  important 
  evidence 
  pertaining 
  to 
  their 
  

   migrations 
  and 
  wintering 
  grounds. 
  (Cf. 
  Lincoln, 
  1927.) 
  Out- 
  

   standing 
  among 
  these 
  returns 
  is 
  the 
  case 
  of 
  a 
  tern 
  banded 
  on 
  the 
  

   coast 
  of 
  Maine 
  and 
  four 
  years 
  later 
  found 
  recently 
  dead 
  at 
  the 
  

   mouth 
  of 
  the 
  Niger 
  River, 
  British 
  West 
  Africa. 
  To 
  date, 
  this 
  is 
  

   the 
  only 
  record 
  of 
  an 
  American 
  banded 
  bird 
  crossing 
  the 
  ocean, 
  

   although 
  several 
  gulls 
  (Larus 
  ridibundus 
  and 
  Rissa 
  tridactyla), 
  

   banded 
  in 
  England 
  and 
  Germany, 
  have 
  been 
  recovered 
  in 
  American 
  

   waters. 
  (Cf. 
  Lincoln, 
  1925.) 
  

  

  Terns 
  banded 
  at 
  colonies 
  on 
  the 
  Atlantic 
  coast 
  have 
  been 
  reported 
  

   south 
  to 
  the 
  mouth 
  of 
  the 
  Chumpan 
  River, 
  in 
  Mexico 
  (pi. 
  3, 
  fig. 
  2), 
  

   Porto 
  Rico, 
  French 
  West 
  Indies, 
  the 
  island 
  of 
  Trinidad, 
  and 
  the 
  

   coast 
  of 
  Venezuela. 
  As 
  one 
  of 
  the 
  narrow 
  parts 
  of 
  the 
  Atlantic 
  

   Ocean 
  is 
  between 
  the 
  coasts 
  of 
  Brazil 
  and 
  western 
  Africa, 
  and 
  in 
  

   view 
  of 
  the 
  other 
  data 
  at 
  hand, 
  it 
  seems 
  reasonable 
  to 
  presume 
  that 
  

   occasionally 
  birds 
  wintering 
  on 
  the 
  northeastern 
  coast 
  of 
  South 
  

   America 
  strike 
  boldly 
  out 
  to 
  sea 
  and 
  cross 
  to 
  the 
  African 
  coast. 
  

  

  Common 
  terns 
  banded 
  at 
  colonies 
  in 
  the 
  Great 
  Lakes 
  also 
  have 
  

   been 
  retaken 
  south 
  to 
  southern 
  Mexico, 
  but 
  they 
  also 
  show 
  a 
  wide 
  

   dispersal 
  throughout 
  the 
  southeastern 
  United 
  States.

  Herring 
  gidl. 
  — 
  The 
  herring 
  gull 
  {Larus 
  argentat-m) 
  has 
  a 
  wide 
  

   distribution 
  in 
  North 
  America, 
  and 
  the 
  large 
  colonies 
  have 
  proved 
  

   attractive 
  fields 
  for 
  banding 
  activities, 
  over 
  6,000 
  having 
  been 
  banded.
