Habits. — The Turnstone is almost exclusively a bird of the sea- 

 shore, though occasionally, especially on migration, found inland ; 

 it prefers rocky places to sandy beaches, and feeds on small Crus- 

 tacea and mollusca, which it obtains by turning over stones and 

 seaweed ; it is wary and difficult to approach, and its note is a clear 

 whistle. 



As aheady stated it is not known definitely to breed in South 

 Africa, but in northern regions its nest is placed on or near the sea- 

 shore, and consists merely of a lining of a few dry leaves or bents 

 in a shallow depression. Pour eggs of a greenish-grey colour spotted 

 and streaked with bluish-ash and brown and measuring 1-6 x 1-1 are 

 laid, and both sexes share in incubation.
