1 82 WATER FOWL. 



least Strong, for I noticed the birds rarely settled on the 

 water where it was running swiftly. This Duck decoys 

 readily in such situations, and will come right in, and if 

 permitted settle among the wooden counterfeits. They 

 sit lightly upon the water and rise at once without effort 

 or much splashing. The flight is very rapid, and is ac- 

 companied with the same whistling of the wings so 

 noticeable in the Common Golden Eye. In stormy 

 weather this bird keeps close to the banks, seeking shel- 

 ter from the winds. It dives as expertly as its relative, 

 and frequently remains under water for a considerable 

 time. The flesh of those killed upon the river was tender 

 and of good flavor, fish evidently not having figured 

 much as an article of their diet.
