146 GAME BIBDS OF CALIFORNIA 



From the foregoing evidence it can be seen that the Wood Duck, 

 although existing in California in considerable numbers in the early 

 days, is now nearly extinct. A number of the eastern states have 

 found it necessary to give it complete and permanent protection in 

 order to save it. California's only hope of saving this species is to 

 do likewise. Although the Wood Duck is migratory in most states, it 

 remains with us throughout the year and so gives us an added respon- 

 sibility. The federal regulations regarding migratory birds which 

 went into effect in the fall of 1913 placed a closed season of five years 

 on the Wood Duck. At the end of this period a renewal of total pro- 

 tection will be necessary.
