   number 
  mentioned

  met 
  with 
  in

   collections 
  (Ibis,

  A 
  long 
  series 
  of 
  interesting 
  

   field-notes 
  on 
  the 
  various 
  species 
  is 
  appended. 
  

  

  " 
  Owing 
  to 
  the 
  enormous 
  abundance 
  of 
  food 
  of 
  all 
  kinds, 
  

   and 
  to 
  the 
  immense 
  uninhabited 
  tracts 
  of 
  forest 
  and 
  savannah 
  

   lands, 
  furnishing 
  splendid 
  shelter 
  and 
  breeding-haunts, 
  in 
  all 
  

   parts 
  of 
  the 
  colony, 
  these 
  birds 
  have 
  multiplied 
  to 
  a 
  remark- 
  

   able 
  extent, 
  the 
  species 
  being 
  not 
  only 
  distributed 
  all 
  over 
  

   the 
  colony, 
  but 
  represented 
  by 
  hosts 
  of 
  individuals 
  to 
  be 
  

   met 
  Avith 
  in 
  all 
  directions. 
  It 
  is 
  along 
  the 
  coast-districts 
  

   generally, 
  however, 
  and 
  more 
  especially 
  along 
  the 
  tidal 
  parts 
  

   of 
  the 
  larger 
  creeks, 
  that 
  these 
  birds 
  are 
  seen 
  in 
  greatest 
  

   profusion 
  and 
  variety 
  — 
  though 
  there 
  are 
  a 
  few 
  larger 
  species, 
  

   such 
  as 
  the 
  Crowned 
  Eagle 
  (Spizaetus), 
  the 
  Crested 
  Eagle 
  

   {Morphnus), 
  the 
  Harpy 
  [Thrasa'etns) 
  , 
  etc., 
  that 
  are 
  met 
  with 
  

   only 
  in 
  the 
  higher 
  parts 
  of 
  the 
  rivers, 
  in 
  the 
  dense 
  recesses 
  

   of 
  the 
  forest, 
  or 
  on 
  the 
  open 
  bushy 
  savannah 
  lands, 
  in 
  which 
  

   latter 
  places 
  also 
  the 
  little 
  Kestrels 
  (Tinnunculus) 
  are 
  most 
  

   commonly 
  to 
  be 
  found.''
