  (Arg.

  This 
  species 
  also 
  appeared 
  at 
  the 
  same 
  time 
  as 
  the 
  other 
  

   migrants 
  and 
  i)assed 
  a 
  week 
  here, 
  when 
  it 
  frequented 
  the 
  trees, 
  

   making 
  rapid 
  flights 
  after 
  insects. 
  Its 
  flight 
  is 
  very 
  erratic 
  

   and 
  powerful. 
  Sometimes 
  it 
  darts 
  upwards 
  to 
  a 
  good 
  height 
  

   with 
  great 
  velocity, 
  at 
  others 
  it 
  dashes 
  through 
  the 
  branches 
  

   at 
  a 
  reckless 
  pace. 
  It 
  was 
  very 
  wary 
  and 
  hard 
  to 
  approach.

  two 
  or

  oft'

  Another 
  doubtful 
  species, 
  obtained 
  at 
  the 
  same 
  time. 
  

   This 
  Tyrant 
  also 
  inhabits 
  trees, 
  and 
  catches 
  insects 
  on 
  the 
  

   wing, 
  but 
  is 
  less 
  shy 
  than 
  the 
  fcjrmer 
  and 
  does 
  not 
  possess 
  

   such 
  a 
  powerful 
  flight. 
  

  

  [The

  are

   young 
  birds 
  of 
  the 
  Black-and-yellow-crested 
  Tyrant, 
  which 
  in 
  

   a 
  subsequent 
  communication 
  Mr. 
  Holland 
  tells 
  me 
  is 
  "fairly 
  

   common 
  " 
  in 
  his 
  district. 
  The 
  head 
  is

  is 
  a 
  

   single 
  feather 
  of

  I 
  think 
  tliis 
  is 
  a 
  female 
  of 
  the 
  Plant-cutter, 
  but, 
  not 
  being 
  

   acquainted 
  with 
  the 
  birds, 
  cannot 
  say 
  for 
  certain. 
  Several 
  of 
  

   this 
  species, 
  all 
  hens 
  or 
  immature 
  birds, 
  stayed 
  here 
  a 
  few 
  

   days 
  on 
  their 
  way 
  north 
  or 
  west, 
  frequenting 
  the 
  trees 
  and 
  

   catching 
  insects, 
  after 
  the 
  manner 
  of 
  the 
  Tyrants, 
  in 
  short 
  

   flights 
  from 
  the 
  topmost 
  branches 
  of 
  trees. 
  Until 
  I 
  shot 
  this 
  

   specimen

  imagined 
  that 
  it 
  was 
  one 
  of 
  the 
  Tyraunidae.
