86 WATER BIRDS 



These habits in the care of the young characterize all 

 species of grebes, for in no birds are the family traits 

 more prominent than among these queer divers. To the 

 shame of all plumage-hunters be it said, the love of the 

 grebes for their young is one cause of the rapid diminu- 

 tion of their number, for so expert are the grebes in div- 

 ing at the flash of the gun that, but for the mother love 

 which impels them to protect their helpless little ones, 

 they could easily escape. But they are mercilessly shot 

 while defending their nests, and the young are left to 

 starve, while the silvery breast of the mother bird adorns 

 the hat of a thoughtless woman.
