  of 
  course 
  limited 
  in 
  numbers. 
  At 
  about 
  4000 
  feet 
  both 
  

   species 
  and 
  specimens 
  reach 
  their 
  maximum. 
  Most 
  abundant 
  

   and 
  widely-ranging 
  of 
  the 
  Finches 
  is 
  the 
  "On" 
  {Loxioides 
  

   bailleui). 
  This 
  bird 
  often 
  goes 
  iu 
  little 
  companies 
  and 
  

   wanders 
  quite 
  below 
  tlie 
  true 
  forest, 
  being 
  partial 
  to 
  the 
  large 
  

   kukui 
  trees. 
  It 
  has 
  a 
  somewhat 
  sweet 
  song, 
  which 
  at 
  times 
  

   reminds 
  one 
  of 
  the 
  Canary, 
  and 
  frequently 
  several 
  will 
  sing 
  

   in 
  concert. 
  I 
  have 
  noticed 
  that 
  it 
  often 
  sings 
  while 
  on 
  

   the 
  wing. 
  It 
  belongs 
  strictly 
  to 
  the 
  lower 
  of 
  the 
  two 
  districts 
  

   that 
  I 
  have 
  mentioned, 
  for 
  its 
  food 
  is 
  mainly 
  the 
  red 
  flower 
  

   of 
  the 
  ieie, 
  but 
  in 
  the 
  interval 
  between 
  the 
  decay 
  of 
  the 
  old 
  

   blossoms 
  and 
  the 
  opening 
  of 
  the 
  new 
  many 
  specimens 
  strayed, 
  

   even 
  up 
  to 
  4000 
  feet, 
  into 
  the 
  haunts 
  of 
  Psittacirostra, 
  when 
  

   the 
  song 
  of 
  both 
  migljt 
  be 
  heard 
  in 
  the 
  same 
  locality. 
  The 
  

   Ou 
  po-papale 
  ( 
  Psittacirostra 
  psittacea) 
  is 
  confined 
  to 
  the 
  upper 
  

   forest, 
  where 
  its 
  chief 
  food 
  (the 
  beans 
  of 
  the 
  mamale) 
  is 
  found 
  ; 
  

   its 
  song 
  is 
  pleasing, 
  but 
  to 
  me 
  less 
  so 
  than 
  that 
  of 
  the 
  Oa. 
  I 
  

   have 
  found 
  by 
  dissection 
  that 
  it 
  is 
  also 
  largely 
  insectivorous, 
  

   being 
  particularly 
  fond 
  of 
  lepidopterous 
  larvae. 
  In 
  one 
  case 
  

   I 
  found 
  an 
  adult 
  male 
  crammed 
  with 
  examples 
  of 
  a 
  brilliant 
  

   yellow, 
  black, 
  and 
  green 
  larva 
  of 
  moderate 
  size 
  which 
  feeds 
  

   on 
  the 
  mamane, 
  and 
  would 
  certainly 
  be 
  regarded 
  as 
  possessing 
  

   in 
  the 
  highest 
  degree 
  the 
  so-called 
  '^ 
  warning 
  colours." 
  This 
  

   species 
  ranges 
  to 
  a 
  considerable 
  height 
  up 
  the 
  mountains. 
  I 
  

   noticed 
  it 
  on 
  Hualalai 
  up 
  to 
  about 
  6000 
  feet. 
  

  

  The 
  Koa 
  Finch 
  {Rlwdacant/tis 
  palineri) 
  is 
  the 
  largest 
  and 
  

   most 
  beautiful 
  of 
  all 
  the 
  Hawaiau 
  Finches. 
  It 
  frequents 
  

   the 
  tallest 
  and 
  most 
  leafy 
  acacias, 
  both 
  when 
  growdng 
  on 
  

   the 
  roughest 
  lava-flows 
  and 
  in 
  the 
  grassy 
  openings 
  in 
  the 
  

   forest. 
  It 
  belongs 
  entirely 
  to 
  the 
  upper 
  forest, 
  and 
  is 
  j^ro- 
  

   bably 
  most 
  numerous 
  at 
  about 
  4000 
  feet. 
  Its 
  peculiar 
  

   whistle, 
  though 
  not 
  very 
  loud, 
  is 
  very 
  clear, 
  and 
  can 
  be 
  

   heard 
  for 
  a 
  considerable 
  distance. 
  If 
  imitated 
  closely 
  it 
  will 
  

   readily 
  answer, 
  and 
  sometimes, 
  after 
  fruitless 
  hunting 
  for 
  

   hours 
  without 
  even 
  hearing 
  a 
  sound 
  from 
  this 
  bird, 
  a 
  whistle 
  

   has 
  been 
  immediately 
  responded 
  to. 
  At 
  other 
  times 
  a 
  distant 
  

   bird 
  has 
  been 
  drawn 
  close 
  by 
  the 
  imitation 
  of 
  its 
  wdiistle 
  and 
  

   easily 
  secured. 
  It 
  devours 
  the 
  beans 
  of 
  the 
  acacia, 
  and 
  these
