494 The Water-fowl Family 



deeper brown, a broad zone of mottled black and white feathers 



extending across the breast. 

 Measurements Wing, 10 inches; tail, 4 inches; tarsus, 2.25 



inches; bill from nostril, 2.35 inches, from feathers, 3 inches; 



depth at angle, .50 inch. 

 Habitat Ranges on both coasts of Lower California and rarely 



north to Ventura County, California, and breeds throughout its 



range. May prove synonymous with H. galapagensis, of the 



Galapagos Islands. 



Closely resembling the American oyster-catcher 

 in appearance, this bird has exactly the same 

 habits. It frequents the shores of the islands of 

 the coast of Lower California and possibly western 

 Mexico. As early as January the bird mates, 

 breeding on the high beaches. 



It keeps close to the water's edge and feeds on 

 small shellfish. It is shy, running rapidly along 

 the beach and giving a clear whistle as it takes 

 flight.
