84 GAME BIRDS OF CALIFOSNIA 



This bird is usually considered poor food, as it is pronounced 

 tough, and at most seasons, has an unpleasant fishy taste. When 

 properly prepared, however, its "gamy" flavor can be appreciated 

 with the aid of a hearty appetite. But the skill needed to bring it to 

 bag, therefore forms its chief claim to being classed as a game bird. 



American Mergansers have been occasionally seen on the market 

 in San Francisco and Sacramento along with other ducks, and hunters 

 are sometimes seen carrying them. No information regarding their 

 comparative numbers now and formerly has been obtainable. But 

 as the hunter often passes them by, and as they are wary and difficult 

 to shoot, it seems probable that there has been no marked decrease in 

 their numbers.
