  ANALYSIS 
  OF 
  THE 
  MAMMALIAN 
  AND 
  AVIAN 
  FAUNA. 
  

  

  comparing 
  the 
  text 
  with 
  the 
  analysis. 
  We 
  have 
  used 
  Saunders's 
  List 
  

   of 
  British 
  Birds, 
  being 
  the 
  latest 
  authority 
  to 
  date. 
  

  

  We 
  have 
  divided 
  the 
  different 
  Faunal 
  Values 
  of 
  the 
  various 
  

   species 
  under 
  the 
  following 
  heads, 
  viz. 
  : 
  — 
  

  

  Eesident, 
  Summer 
  Visitants, 
  Winter 
  Visitants, 
  Autumn 
  and 
  

   Spring 
  Migrants, 
  Occasional 
  — 
  i.e. 
  Irregular 
  Visitants, 
  Doubt- 
  

   fully-recorded 
  species, 
  Introduced 
  and 
  Escaped 
  species 
  (the 
  

   latter 
  being, 
  as 
  may 
  be 
  understood, 
  such 
  as 
  have 
  escaped 
  from 
  con- 
  

   finement 
  or 
  from 
  private 
  ornamental 
  waters), 
  and 
  species 
  which 
  

   Occasionally 
  Nest. 
  

  

  Eesidents 
  are 
  those 
  species 
  which 
  remain 
  the 
  whole 
  year 
  round, 
  and 
  

   breed 
  regularly 
  in 
  some 
  part 
  or 
  parts 
  of 
  the 
  area, 
  it 
  may 
  be 
  even 
  in 
  only 
  

   one 
  locality. 
  

  

  Summer 
  Visitants 
  are 
  such 
  as 
  nest 
  regularly, 
  but 
  are 
  only 
  within 
  

   the 
  area 
  during 
  the 
  breeding 
  season. 
  

  

  Winter 
  Visitants 
  are 
  those 
  that 
  remain 
  all 
  winter, 
  arriving 
  in 
  

   autumn, 
  and 
  leaving 
  in 
  spring. 
  

  

  Autumn 
  and 
  Spring 
  Migrants 
  are 
  those 
  that 
  occur 
  on 
  either 
  or 
  both 
  

   migrations, 
  but 
  not 
  at 
  other 
  times. 
  

  

  Occasional 
  Visitants 
  occur 
  at 
  irregular, 
  or 
  to 
  us, 
  at 
  present, 
  from 
  

   unaccountable 
  reasons. 
  

  

  Doubtfully 
  recorded 
  species 
  are 
  such 
  as 
  have 
  been 
  included 
  on 
  

   insufficient 
  data, 
  or 
  the 
  specimens 
  or 
  history 
  of 
  which 
  have 
  been 
  lost. 
  

  

  Introduced 
  species 
  (not 
  naturalised 
  like 
  the 
  Pheasant) 
  are 
  those 
  

   which 
  have 
  been 
  introduced 
  of 
  late 
  years. 
  This 
  also 
  embraces 
  Escaped 
  

   species, 
  as 
  we 
  have 
  already 
  indicated. 
  1 
  

  

  Species 
  that 
  nest 
  occasionally, 
  sometimes 
  in 
  considerable 
  numbers, 
  

   but 
  are, 
  as 
  yet, 
  not 
  known 
  to 
  breed 
  regularly. 
  

  

  Some 
  of 
  the 
  birds 
  mentioned 
  in 
  our 
  analysis 
  will 
  be 
  found 
  under 
  

   more 
  than 
  one 
  heading. 
  Thus 
  the 
  Short-eared 
  Owl 
  will 
  be 
  found 
  as 
  

   Occasionally 
  Nesting, 
  and 
  also 
  as 
  an 
  Autumn 
  Visitant. 
  Further 
  

   search 
  may 
  prove 
  that 
  it 
  nests 
  more 
  regularly, 
  or 
  is 
  an 
  increasing 
  or 
  de-

  It 
  is 
  much 
  to 
  be 
  desired 
  that 
  those 
  who 
  possess 
  aviaries 
  or 
  ornamental 
  water- 
  

   fowl, 
  or 
  even 
  caged 
  birds, 
  anywhere 
  in 
  Scotland, 
  should 
  give 
  notice 
  of 
  ' 
  Escapes,' 
  and 
  

   also 
  furnish 
  lists 
  of 
  species 
  which 
  may 
  occupy 
  any 
  locality 
  in 
  a 
  semi-domesticated 
  

   state, 
  and 
  such 
  data 
  as 
  time 
  of 
  introduction, 
  and 
  details 
  of 
  nesting, 
  and 
  of 
  increase 
  

   or 
  decrease 
  at 
  the 
  said 
  localities. 
  While 
  interesting 
  in 
  themselves, 
  such 
  details, 
  if 
  

   duly 
  recorded, 
  would 
  often 
  save 
  much 
  uncertainty, 
  trouble, 
  and 
  confusion 
  to 
  the 
  

   recording 
  naturalists 
  working 
  at 
  our 
  native 
  fauna.
