  migration. 
  Northeastward 
  the 
  species 
  is 
  known 
  as 
  a 
  rare 
  migrant, 
  in 
  

   New 
  England 
  hardly 
  more 
  than 
  a 
  straggler, 
  but 
  it 
  has 
  been 
  recorded 
  

   as 
  far 
  as 
  Newfoundland, 
  southern 
  Labrador 
  (Natashquan), 
  and 
  north- 
  

   ern 
  Ontario 
  (Moose 
  River). 
  The 
  baldpate 
  is 
  rather 
  rare 
  on 
  the 
  coast 
  

   of 
  Alaska, 
  but 
  is 
  more 
  common 
  in 
  the 
  interior, 
  and 
  is 
  a 
  rare 
  or 
  casual 
  

   visitor 
  to 
  the 
  Near, 
  Commander, 
  and 
  Bermuda 
  islands.

  — 
  The 
  baldpate 
  is 
  common 
  on 
  the 
  Chesapeake 
  in 
  win- 
  

   ter, 
  but 
  as 
  it 
  is 
  rare 
  directhy 
  to 
  the 
  northward 
  at 
  all 
  times 
  of 
  the 
  year, 
  

   it 
  is 
  evident 
  that 
  the 
  migration 
  is 
  from 
  the 
  northwest.

   birds 
  are 
  found 
  in 
  winter 
  as 
  far 
  north 
  as 
  Rhode 
  Island. 
  The 
  species 
  

   is 
  common 
  during 
  the 
  winter 
  in 
  the 
  Carolinas, 
  less 
  common 
  in 
  Florida 
  

   and 
  Cuba, 
  and 
  rare 
  in 
  the 
  Bermudas, 
  the 
  Bahamas, 
  Jamaica, 
  Porto 
  

   Rico, 
  St. 
  Thomas, 
  and 
  Trinidad. 
  It 
  is 
  recorded 
  from 
  Costa 
  Rica, 
  and 
  

   is 
  a 
  rather 
  common 
  winter 
  resident 
  of 
  northern 
  Guatemala 
  and 
  much 
  

   of 
  Mexico 
  north 
  of 
  the 
  Valley 
  of 
  Mexico. 
  The 
  winter 
  home 
  in 
  the 
  

   Mississippi 
  Valley 
  extends 
  north 
  to 
  Illinois, 
  and 
  in 
  the 
  west 
  to 
  New 
  

   Mexico, 
  Arizona, 
  Utah 
  (probably), 
  and 
  to 
  southern 
  British 
  Columbia. 
  

   It 
  is 
  probably 
  most 
  common 
  during 
  the 
  winter 
  along 
  the 
  Pacific 
  coast. 
  

   Spring 
  migration* 
  — 
  This 
  begins 
  late 
  in 
  February 
  and 
  by 
  early 
  March 
  

   the 
  species 
  is 
  north 
  of 
  its 
  winter 
  home. 
  Average 
  dates 
  of 
  arrival 
  are: 
  

   Western 
  New 
  York, 
  March 
  23 
  ; 
  Erie, 
  Pa., 
  March 
  24; 
  Oberlin, 
  Ohio, 
  

   March 
  17; 
  southern 
  Michigan, 
  March 
  25; 
  Keokuk, 
  Iowa, 
  March 
  15; 
  

   central 
  Nebraska, 
  March 
  17; 
  Loveland, 
  Colo., 
  March 
  10. 
  The 
  further 
  

   advance 
  of 
  the 
  species 
  is 
  somewhat 
  slow. 
  The 
  average 
  time 
  of 
  reach- 
  

   ing 
  Heron 
  Lake, 
  Minn., 
  is 
  March 
  29; 
  southern 
  Manitoba, 
  April 
  20; 
  

   Terry, 
  Mont., 
  April 
  8. 
  The 
  first 
  individual 
  was 
  seen 
  at 
  Indian 
  Head, 
  

   Saskatchewan, 
  April 
  21, 
  1901, 
  and 
  at 
  Osier, 
  Saskatchewan, 
  May 
  2, 
  1893. 
  

   These 
  dates 
  indicate 
  an 
  average 
  speed 
  of 
  17 
  miles 
  per 
  day 
  from 
  central 
  

   Nebraska 
  to 
  Heron 
  Lake, 
  and 
  18 
  miles 
  per 
  day 
  thence 
  to 
  southern 
  

   Manitoba. 
  The 
  average 
  rate 
  from 
  Colorado 
  to 
  Montana 
  is 
  16 
  miles 
  

   per 
  day, 
  and 
  the 
  same 
  rate 
  continued 
  northward 
  would 
  bring 
  the 
  first 
  

   baldpate 
  to 
  Indian 
  Head 
  and 
  Osier 
  at 
  almost 
  exactly 
  the 
  stated 
  dates. 
  

   If 
  the 
  birds 
  of 
  the 
  Mississippi 
  Valley 
  pass 
  northwest 
  to 
  the 
  Mackenzie 
  

   Valley, 
  this 
  rate 
  of 
  migration 
  would 
  bring 
  them 
  to 
  Great 
  Slave 
  Lake 
  

   about 
  the 
  first 
  week 
  in 
  June, 
  whereas 
  the 
  first 
  arrival 
  at 
  Fort 
  Simp- 
  

   son, 
  Mackenzie, 
  was 
  April 
  28, 
  1901; 
  and 
  a 
  female 
  was 
  shot 
  at 
  Fort 
  

   Resolution 
  May 
  21, 
  1860, 
  which 
  contained 
  a 
  fully 
  formed 
  egg. 
  It 
  is 
  

   evident, 
  then, 
  that 
  the 
  earliest 
  arrivals 
  in 
  the 
  Mackenzie 
  Valley 
  come 
  

   from 
  the 
  southwest, 
  where, 
  in 
  southern 
  British 
  Columbia, 
  the 
  species 
  

   winters 
  a 
  thousand 
  miles 
  farther 
  north 
  than 
  on 
  the 
  plains. 
  The 
  bald- 
  

   pate 
  arrives 
  at 
  the 
  mouth 
  of 
  the 
  Yukon 
  in 
  early 
  May, 
  and 
  on 
  the 
  Knik 
  

   River, 
  Alaska, 
  the 
  first 
  bird 
  was 
  noted 
  May 
  10, 
  190J 
  . 
  Most 
  of 
  the 
  

   few 
  spring 
  records 
  in 
  New 
  England 
  are 
  in 
  April, 
  two 
  in 
  February, 
  

   but 
  the 
  species 
  is 
  apparently 
  less^ 
  common 
  in 
  the 
  spring 
  than 
  in 
  the 
  

   fall. 
  The 
  last 
  migrants 
  usually 
  leave 
  Cuba 
  late 
  in 
  April, 
  though 
  in 
  

   Guatemala 
  they 
  have 
  been 
  seen 
  as 
  late 
  as 
  May.
