 I have frequently seen considerable assemblages in early  
 autumn when the birds were evidently congregating  for  
 departure.  As a rule, I have found the Thick-knee very  
 wary, but it  occasionally  attempts  to  avoid  observation  
 by squatting or standing motionless, trusting, no  doubt,  
 to the similarity of its inconspicuous upper plumage to its  
 surroundings for concealment.  From my own experience  
 I think that this habit is generally adopted on the approach  
 of a wheeled vehicle or of a person on horseback;  and in  
 Spain, where the bird is very common, I should frequently  
 have  passed  solitary  individuals  if  it  had not been for  
 the glistening of their bright  yellow  irides  in  the  sunlight. 
   Although  these  birds  are  specially addicted  to  
 perfectly bare and open  wastes,  I  have  frequently  seen  
 them flushed from plantations of  young conifers  on  the  
 sands of Norfolk, and Professor A. Newton has recorded  
 a case in  which a pair frequented a  spot  in  a  covert  of  
 more than three hundred acres at Elveden,  Suffolk, lone  
 after  it  had  become  the  centre  of a flourishing wood.  
 The  principal  food  of  this  species  consists  of  beetles,  
 snails,  mice,  slugs,  and  worms,  frogs  also  are  very  
 favourite morsels,  and  the  birds  “ flight ”  regularly  at  
 nightfall from their  diurnal haunts to the nearest marshy  
 lands in search of these  delicacies.  The  eggs,  two  in  
 number,  are laid upon the  bare  ground,  and  in  colour  
 so closely  resemble  their  sandy  or  flinty  surroundings  
 that  they  are  often  very  difficult  to  find.  A  most  
 interesting account of close  observation of a pair of  this  
 species at their nesting-place is given by Mr. A. Trevor-  
 Battye in a very fascinating work  entitled  ‘ Pictures in 
 Prose, etc.’  (Longmans & Co.,  1894).  This  bird  feeds  
 principally at night, and in  Spain, when riding by moonlight, 
  I have frequently been startled by a sudden clamour  
 of “ Alcaravanes ” passing overhead on their way to their  
 feeding-grounds.  The cry is loud and  clear, but to my  
 ears somewhat mournful and  querulous, well in keeping  
 with the lonely and uninhabited localities so  beloved  of  
 our bird.  In captivity the Thick-knee thrives well,  and  
 from its  semi-confident  hesitating  manners  and  extraordinary  
 speed  on  foot,  with  frequent  relapses  into  
 complete immobility, is a very  attractive  denizen  of  an  
 aviary.  This species is to be met with in suitable localities  
 throughout  Central  and  Southern  Europe  and  North  
 Africa during the summer,  and  very  frequently,  if  not  
 generally, passes the winter in the countries that border  
 the  Mediterranean.  The  Thick-knee;  though  a  very  
 powerful flyer, has but little chance of escape from a good  
 Falcon,  and in my experience seems to be well aware of  
 this fact,  as although it will turn down wind and fly close  
 to the ground at great speed, it shrieks pitifully, and will  
 plunge  headlong  into  the  first  furze-bush,  patch  of  
 bracken, or rabbit-burrow  that  it  can  reach.  I  have  
 kept several of these birds captured in this way alive  at  
 Lilford for  considerable  periods.  In  my  opinion  the  
 Thick-knee is altogether worthless for  the table,  but  in  
 Spain there is a tradition (no doubt handed  down  from  
 the Moors)  that  the  flesh  of  this  bird  if  eaten  warm  
 endows its consumer with strong  sight  and  fleetness  of  
 foot.
