YOUNG BIRDS IN THE NURSERY 59 



she enlarged the hole . . . and then contentedly settled 

 down, purring and jerking her tail all the time." After 

 an hour's vigil, waiting for the next step, the bird was 

 aroused by the approach of a keeper, and bolted. Miss 

 Turner then sent the keeper to examine the eggs and 

 report progress. Two of the young were out, and he 

 removed the broken shells. " Then the excitement began. 

 The female returned, stood on tiptoe, peeped into the

 cases, if taken up in the hand they will even feign death. 

 Birds so unlike as young Norfolk plovers and young
