344 GAME BISDS OF CALIFOBNIA 



has obtained in the ease of more desirable game species, snch as the 

 curlew. As the Avocet affects a type of habitat not encroached upon 

 by agricultural development, its breeding and feeding ranges have not 

 been measurably restricted. The large size of this wader combined 

 with its striking coloration and its open habitat render it a conspicuous 

 object for pursuit, though this is offset to some degree by its rapidly 

 acquired wariness when repeatedly molested. It would appear that 

 a brief open season early in the fall and limited bag, for the benefit of 

 those hunters who care for this bird, might be safely allowed as long 

 as present conditions remain unchanged.
