  in 
  the 
  head, 
  I 
  was 
  unable 
  to 
  determine 
  the 
  color 
  of 
  the 
  eyes 
  in 
  the 
  specimen 
  

   obtained. 
  I 
  presume 
  the 
  bird 
  to 
  be, 
  like 
  the 
  species 
  found 
  at 
  Unalashka, 
  a 
  

   resident. 
  

  

  2. 
  Haliaetus 
  leucocephalus, 
  Sav. 
  (43). 
  Bald 
  Eagle. 
  

  

  Observed 
  at 
  Attn, 
  and 
  a 
  resident 
  throughout 
  the 
  Aleutian 
  chain 
  ; 
  every- 
  

   where 
  occurring 
  in 
  the 
  greatest 
  abundance. 
  So 
  far 
  as 
  my 
  observations 
  go, 
  it 
  

   does 
  not 
  confine 
  its 
  diet 
  to 
  fish, 
  but 
  also 
  destroys 
  grouse 
  and 
  other 
  birds. 
  At 
  the 
  

   time 
  when 
  we 
  left 
  the 
  islands, 
  in 
  October, 
  the 
  young 
  of 
  the 
  year 
  were 
  still 
  un- 
  

   able 
  to 
  fly. 
  H. 
  pelagicus 
  has 
  not 
  yet 
  been 
  obtained 
  from 
  American 
  territory. 
  It 
  

   is 
  found 
  at 
  Petropavlovsk, 
  Kamchatka 
  ; 
  but 
  I 
  believe 
  that 
  it 
  cannot 
  properly 
  

   be 
  included 
  in 
  our 
  fauna. 
  A. 
  canadensis 
  was 
  not 
  observed 
  to 
  the 
  westward. 
  

  

  3. 
  Brachyotus 
  palustris, 
  (52). 
  Short-eared 
  Owl. 
  

  

  Observed 
  in 
  all 
  the 
  islands 
  from 
  Attu 
  eastward. 
  A 
  resident.

  banks. 
  

  

  4. 
  Hirundo 
  horreorum, 
  Barton. 
  (225). 
  Barn 
  Swallow. 
  

  

  This 
  species 
  was 
  obtained 
  abundantly 
  at 
  Unalashka, 
  on 
  and 
  after 
  June 
  9th, 
  

   1873. 
  It 
  is 
  said 
  to 
  nest 
  in 
  the 
  upper 
  portion 
  of 
  the 
  church 
  and 
  other 
  build- 
  

   ings 
  at 
  the 
  village 
  of 
  Iliuliuk. 
  A 
  swallow 
  is 
  also 
  reported 
  as 
  occurring 
  at 
  

   Atka, 
  which 
  is 
  probably 
  the 
  same 
  species. 
  It 
  does 
  not 
  occur 
  at 
  Attu.

  5. 
  Troglodytes 
  hyemalis, 
  var. 
  alascensis, 
  Bd. 
  (293). 
  Wren. 
  

  

  Obtained 
  in 
  Attu 
  and 
  the 
  Pribylofif 
  Islands, 
  a 
  resident 
  throughout 
  the 
  Aleu- 
  

   tian 
  chain, 
  and 
  everywhere 
  very 
  abundant 
  and 
  tame 
  ; 
  but 
  we 
  have 
  not 
  yet 
  been 
  

   able 
  to 
  discover 
  the 
  nest 
  and 
  eggs, 
  though 
  the 
  young 
  birds 
  were 
  very 
  plentiful 
  

   in 
  Amchitka 
  in 
  July. 
  

  

  6. 
  Leucostide 
  griseinucha, 
  Bon. 
  (323). 
  Gray-necked 
  Finch. 
  

  

  The 
  westernmost 
  point 
  at 
  which 
  this 
  species 
  was 
  obtained 
  was 
  Kyska. 
  It 
  

   was 
  not 
  observed 
  at 
  Adakh 
  or 
  Amchitka, 
  but 
  occurs 
  in 
  all 
  the 
  larger 
  islands 
  

   east 
  of 
  Kyska. 
  It 
  is 
  a 
  resident, 
  and 
  breeds 
  in 
  May. 
  I 
  have 
  observed 
  no 
  tran- 
  

   sitional 
  forms 
  in 
  the 
  Aleutian 
  Islands 
  which 
  would 
  connect 
  this 
  race 
  with 
  Ht- 
  

   toralis. 
  

  

  7. 
  Pledrophanes 
  nivalis, 
  Lin. 
  (325). 
  Snowbird. 
  

  

  A 
  resident 
  ; 
  universal 
  throughout 
  the 
  Aleutian 
  and 
  Pribyloff 
  Islands. 
  A 
  

   nest 
  with 
  five 
  eggs, 
  in 
  a 
  fresh 
  condition, 
  was 
  obtained 
  on 
  a 
  low 
  grassy 
  bank, 
  

   June 
  20tb, 
  1873, 
  at 
  Chichagofif 
  Harbor, 
  Attu. 
  Another 
  nest, 
  with 
  four 
  much 
  

   developed 
  eggs, 
  was 
  obtained 
  June 
  23d, 
  in 
  a 
  similar 
  locality. 
  

  

  8. 
  Pledrophanes 
  lapponicus, 
  Selby. 
  (326). 
  Lapland 
  Longspur. 
  

  

  A 
  nest 
  with 
  four 
  much-incubated 
  eggs 
  was 
  obtained 
  at 
  Attu, 
  June 
  18th,
