PERDICIN^. 
These  small  birds  are  scattered  in  the  warmer  and  temperate  parts  of  the  Old  World  and  Australia.  They  migrate 
in  large  flocks  from  the  temperate  countries  to  the  warmer  localities  on  the  approach  of  the  cold  season.  It  is  in  well- 
cultivated  districts  that  they  are  more  generally  found  in  pairs,  amongst  the  tufts  of  grass,  near  water-courses  and 
ponds.  Some  species  prefer  only  rocky  places  amidst  low  bushes,  others  the  elevated  table  lands  and  slopes  of  the 
mountains,  among  the  tufts  of  reeds  and  grass.  Their  food  consists  of  grain,  various  kinds  of  seeds,  insects,  and  worms. 
The  nest  is  scratched  on  the  ground  in  the  form  of  a slight  hollow,  wherein  the  female  deposits  from  six  to  fourteen 
eggs.

* This  genus  was  published  in  the  Encyclopme  MHhodique  by  Bonnaterre  in  1790.  Cryplonyx  (\3\5)  of  M.  Temminck,  and 
(1816)  of  Vieillot  are  synonymous.  ’ 
+ M.  Kaup  established  this  genus  in  1829  (Naturl.  Syst.  p.  183.).  Chacura  (1837)  of  Mr.  Hodgson  is  synonymous;  this  he  changed 
in  1844  to  Pyctes.  It  embraces  Alectoris  of  Mr.  Kaup  (1829).
