LIFE SKETCHES OF DUCKS IN FLIGHT. 



Size may at times give a clue. The dif- 

 ferences in size between grebes, ducks 

 and coots, are not marked when the 

 birds are alone, as is usually the case, 

 so that direct comparison is impos- 

 sible. The smaller ducks, such as teal, 

 have practically the same size as pied- 

 billed grebes. Form is a surer guide. 



One can usually approach any of these 

 birds closely enough to recognize them 

 by their outlines. When in doubt ap- 

 proach the bird till it flies or dives ; its 

 actions should furnish the necessary 

 clue. If it persist in diving refusing to 

 fly, the chances are that it is a grebe 

 or a loon ; size should tell you which.
