LESSER SCAUP DUCK. 167 



for the table. But if fed upon roots of water plants, wild 

 rice, celery, or other similar tender grasses, it is a very 

 good little bird indeed. For the sportsman there is no 

 better object upon which to try his skill than this Duck; 

 its rapid flight and quick, unexpected movements on the 

 wing frequently bringing to nought the efforts of the 

 most expert gunner. 



Considerable variation among individuals of this spe- 

 cies exists in their measurements, and occasionally they 

 approach in size those of the Big Scaup, so that, as re- 

 gards the females, it is at times very difficult to distin- 

 guish which species is represented. Adult males can 

 easily be identified, no matter what their dimensions may 

 be, the metallic hues of the head making them readily 

 recognizable. But there is little in the coloring of the 

 females to separate them from the larger species, and if 

 the wing should exceed eight and one-quarter inches 

 in length it is exceedingly difficult to say to which form 

 the bird should be referred. The company the specimen 

 kept when it was killed, if that could be ascertained, 

 would be the surest test for identification, as these two 

 Scaups are rarely found associating together. The eggs 

 also vary greatly in their measurements.
