﻿64 
  Lieut, 
  H. 
  E. 
  Barnes 
  on 
  the 
  Birds 
  of 
  Aden. 
  

  

  intention 
  of 
  sending 
  it 
  to 
  the 
  Zoological 
  Society 
  of 
  London, 
  

   as 
  soon 
  as 
  lie 
  could 
  make 
  satisfactory 
  arrangements. 
  

  

  2. 
  Neophron 
  percnopterus 
  (Linn.). 
  

  

  I 
  do 
  not 
  agree 
  with 
  Major 
  Yerbury 
  in 
  thinking 
  that 
  the 
  

   Egyptian 
  Vulture 
  is 
  a 
  permanent 
  resident, 
  as 
  during 
  June, 
  

   July, 
  and 
  August 
  scarcely 
  one 
  can 
  be 
  seen, 
  but 
  before 
  and 
  

   after 
  these 
  months 
  they 
  are 
  very 
  common. 
  Many 
  white 
  

   birds 
  on 
  their 
  return 
  in 
  October 
  are 
  accompanied 
  by 
  others 
  

   in 
  the 
  nesting-plumage. 
  This 
  certainly 
  goes 
  to 
  prove 
  that 
  

   most 
  of 
  them 
  leave 
  us 
  for 
  breeding 
  purposes, 
  but 
  some 
  few 
  

   may, 
  and 
  possibly 
  do, 
  remain 
  all 
  the 
  year 
  round. 
  

  

  They 
  roost 
  at 
  night 
  in 
  caves 
  in 
  the 
  high 
  cliffs 
  near 
  the 
  

   Main 
  Pass 
  Gate 
  and 
  other 
  suitable 
  places, 
  and 
  the 
  cliffs 
  at 
  

   these 
  spots 
  are 
  conspicuously 
  whitened 
  by 
  their 
  droppings. 
  

  

  Of 
  the 
  other 
  two 
  species 
  of 
  Vulture 
  believed 
  by 
  Major 
  

   Yerbury 
  to 
  occur 
  in 
  the 
  neighbourhood 
  of 
  Aden, 
  one 
  is 
  

   possibly 
  Gyps 
  fulvus, 
  already 
  mentioned, 
  and 
  the 
  other 
  

   immature 
  specimens 
  of 
  Neophi-on 
  percnopterus. 
  

  

  Captain 
  Bishop, 
  the 
  Port 
  Officer, 
  first 
  drew 
  my 
  attention 
  

   to 
  the 
  fact 
  that 
  the 
  birds 
  left 
  us 
  in 
  the 
  commencement 
  of 
  

   June, 
  and 
  in 
  his 
  opinion 
  not 
  a 
  single 
  Neophron 
  ever 
  remains 
  

   to 
  breed 
  at 
  Aden. 
  

  

  3. 
  Falco 
  peregrinus, 
  Tunst. 
  

  

  I 
  frequently 
  observed 
  a 
  pair 
  of 
  birds, 
  near 
  the 
  Main 
  Pass 
  

   Gate, 
  which 
  I 
  think 
  were 
  Peregrine 
  Falcons, 
  and 
  regret 
  that 
  

   I 
  did 
  not 
  shoot 
  one 
  of 
  them 
  to 
  make 
  sure 
  ; 
  but 
  the 
  fact 
  is 
  

   that 
  the 
  birds 
  resident 
  in 
  Aden 
  are 
  so 
  few 
  in 
  number 
  that 
  

   I 
  did 
  not 
  care 
  to 
  shoot 
  even 
  one 
  unnecessarily. 
  

  

  I 
  am 
  of 
  opinion 
  that 
  they 
  had 
  a 
  brood 
  close 
  by, 
  but 
  the 
  

   rocks 
  were 
  inaccessible, 
  and 
  as 
  I 
  never 
  saw 
  more 
  than 
  the 
  

   pair 
  I 
  cannot 
  be 
  certain. 
  I 
  could 
  see 
  sticks 
  projecting 
  

   from 
  a 
  ledge 
  of 
  rock 
  which 
  they 
  much 
  aflFected 
  ; 
  still 
  this 
  

   may 
  only 
  have 
  been 
  an 
  old 
  nest 
  belonging 
  to 
  a 
  Kite. 
  

  

  4. 
  Falco 
  barbarus, 
  Linn. 
  

  

  A 
  female 
  specimen 
  obtained 
  near 
  Lahej, 
  on 
  the 
  23rd 
  

   October, 
  which 
  I 
  doubtfully 
  identified 
  as 
  Falco 
  peregrinus^
