The Black Turnstone is common along the coast dis- 

 trict of California throughout all the year. Mr. Grinnell 

 says that although a few individuals remain all summer, 

 they are not known to breed within the confines of the 

 State. They are seen most frequently along the exposed 

 ocean beaches, where their curious habit of poking under 

 small stones for food has given them their name. They 

 may be known by their short, sharp, tip-tilted bill, black 

 head, and white rump. There are but four species in 

 the family, three of which occur in the United States. 

 Of these the Black Turnstone is the only one met with 

 frequently in California, although the Ruddy Turnstone 

 occurs as a migrant throughout the coast district. All 

 the species are strictly maritime birds, living on the outer 

 beaches and shunning the interior.
