  Colymbus 
  arcticus, 
  L. 
  Black-throated 
  Diver. 
  

   This 
  bird 
  is 
  often 
  called 
  the 
  Great 
  Northern 
  Diver. 
  

  

  A 
  common 
  species 
  in 
  the 
  extreme 
  north 
  of 
  our 
  area, 
  but 
  by 
  no 
  

   means 
  numerous 
  south 
  of 
  the 
  Great 
  Glen. 
  In 
  Sutherland 
  it 
  is 
  

   abundant, 
  and 
  also 
  in 
  the 
  neighbourhood 
  of 
  Invergarry, 
  but 
  from 
  

   what 
  Mr. 
  Malcolm 
  tells 
  us 
  this 
  is 
  rather 
  a 
  recent 
  extension. 
  

   He 
  says 
  : 
  — 
  ' 
  Nearly 
  every 
  loch 
  in 
  the 
  district 
  holds 
  a 
  pair 
  or 
  two 
  

   of 
  these 
  birds 
  every 
  year 
  now, 
  but 
  formerly 
  Loch 
  Lundy 
  was 
  the 
  

   only 
  loch 
  they 
  visited. 
  They 
  breed.' 
  We 
  have 
  ourselves 
  seen 
  

   them 
  both 
  on 
  Loch 
  Lundy 
  and 
  other 
  lochs 
  in 
  the 
  vicinity. 
  

  

  Of 
  its 
  breeding 
  range 
  south 
  of 
  the 
  Ness 
  we 
  have 
  not 
  the 
  very 
  

   fullest 
  data. 
  From 
  1845 
  to 
  about 
  1851 
  the 
  Black- 
  throated 
  Diver 
  

   bred 
  regularly 
  at 
  Lochandorb, 
  as 
  we 
  are 
  assured 
  by 
  Lewis 
  Dunbar. 
  

   We 
  know 
  it 
  breeds 
  at 
  Loch 
  Ruthven, 
  whence 
  we 
  have 
  seen 
  the 
  

   eggs, 
  and 
  we 
  have 
  ourselves 
  seen 
  the 
  birds 
  upon 
  the 
  west 
  end 
  of 
  

   Loch 
  Errochd, 
  upon 
  the 
  extreme 
  borders 
  of 
  our 
  present 
  area. 
  St. 
  

   John 
  remarked 
  that 
  this 
  species 
  bred 
  on 
  Lochandorb, 
  and 
  in 
  no 
  

   other 
  loch 
  in 
  the 
  district. 
  Another 
  locality 
  for 
  it 
  south 
  of 
  the 
  

   Great 
  Glen 
  is 
  Loch 
  Knockie. 
  One 
  in 
  full 
  summer 
  plumage, 
  and 
  

   others 
  in 
  winter 
  plumage, 
  are 
  in 
  Duff 
  House 
  collection 
  — 
  1 
  all 
  killed 
  

   off 
  the 
  coast 
  ' 
  (auct. 
  Mowat, 
  gamekeeper). 
  It 
  occurs 
  occasionally 
  

   in 
  Findhorn 
  Bay; 
  one 
  obtained 
  there 
  in 
  1855 
  was 
  sent 
  to 
  the 
  

   Dalvey 
  Museum. 
  The 
  species 
  is 
  not 
  very 
  abundant, 
  though 
  

   young 
  birds 
  occur 
  in 
  winter. 
  

  

  Brown 
  of 
  Forres 
  writes, 
  under 
  date 
  of 
  14/v/95 
  : 
  — 
  'As 
  I 
  am 
  

   writing, 
  a 
  fine 
  specimen 
  of 
  a 
  Black-throated 
  Diver 
  has 
  just 
  come 
  to 
  

   hand. 
  Strange 
  to 
  say, 
  it 
  is 
  from 
  the 
  mid 
  station 
  (salmon-net 
  

   station), 
  between 
  Findhorn 
  and 
  Burghead. 
  For 
  the 
  last 
  fifteen 
  

   years 
  they 
  have 
  been 
  caught 
  at 
  that 
  station. 
  I 
  have 
  never 
  seen 
  

   one 
  which 
  was 
  obtained 
  on 
  any 
  other 
  part 
  of 
  the 
  coast.' 
  

  

  Colymbus 
  septentrionalis, 
  L. 
  Red-throated 
  Diver. 
  

  

  A 
  fairly 
  common 
  species 
  in 
  summer 
  in 
  the 
  north 
  part 
  of 
  our 
  area, 
  

   though 
  by 
  no 
  means 
  so 
  abundant 
  as 
  the 
  Black-throat 
  ; 
  in 
  the 
  

   winter, 
  however, 
  this 
  is 
  reversed. 
  Mr. 
  Malcolm 
  says 
  of 
  this 
  

   species 
  about 
  Invergarry 
  : 
  — 
  1 
  Not 
  quite 
  so 
  numerous 
  as 
  the 
  Black- 
  

   throated 
  — 
  still 
  a 
  good 
  few 
  — 
  they 
  also 
  breed.' 
  

  

  Curiously 
  the 
  O.S.A. 
  is 
  utterly 
  silent 
  as 
  to 
  any 
  species 
  of 
  Diver 
  

   (Colymbus) 
  in 
  Moray.
