  Birds

  mens 
  from 
  Bonaire 
  are

  while 
  those 
  of 
  C. 
  pertinax 
  from 
  Cura(jao 
  are 
  — 
  total 
  

   length 
  about 
  10 
  inches,

  Having 
  said 
  so 
  much 
  about 
  the 
  Parrakeet 
  of 
  Bonaire, 
  I 
  

   must 
  add 
  that 
  it 
  is 
  extremely 
  common 
  and 
  numerous 
  in 
  almost 
  

   every 
  place 
  in 
  the 
  island 
  where 
  the 
  country 
  is 
  not 
  quite 
  bare. 
  

   The 
  screaming 
  of 
  these 
  lovely 
  birds 
  is 
  about 
  the 
  commonest 
  

   noise 
  that 
  is 
  heard 
  in 
  the 
  bush 
  on 
  Bonaire, 
  but 
  they 
  are 
  often 
  

   rather 
  shy. 
  The 
  yellow 
  head 
  of 
  the 
  adult 
  is 
  so 
  clearly 
  

   visible 
  that 
  even 
  a 
  geological 
  traveller 
  like 
  Professor 
  Martin 
  

   noticed 
  it, 
  and 
  has 
  distinctly 
  said 
  that 
  the 
  bird 
  is 
  of 
  a 
  species 
  

   different 
  from 
  C. 
  pertinax. 
  

  

  Whether 
  ornithologists 
  are 
  inclined 
  to 
  call 
  it 
  a 
  species 
  or 
  

   a 
  subspecies 
  matters 
  little, 
  but 
  it 
  is 
  certainly 
  different 
  from 
  

   the 
  Conurus 
  of 
  Cura9ao.

  POLYBORUS 
  CHERIWAY 
  (Jacq.). 
  

  

  Occurs 
  everywhere, 
  but 
  not 
  in 
  large 
  numbers. 
  These 
  birds 
  

   are 
  often 
  killed 
  because 
  they 
  are 
  supposed 
  to 
  destroy 
  the 
  

   chickens. 
  Besides 
  the 
  preceding 
  species, 
  I 
  conclude 
  from 
  the, 
  

   reports 
  of 
  the 
  inhabitants 
  that 
  several 
  other 
  birds 
  of 
  prey, 
  

   and 
  among 
  these 
  Falco 
  peregrinus 
  and 
  Pandion 
  haliaetus, 
  

   visit 
  this 
  island, 
  as 
  well 
  as 
  Aruba 
  and 
  Curacao, 
  in 
  the 
  

   winter. 
  

  

  There 
  appear 
  to 
  be 
  no 
  Owls 
  in 
  Bonaire.
