456 Tbe Water-fowl Family 



lish lakes. Here they frequent the upper slopes 

 of the highest mountains, laying their eggs in a 

 small hollow which they form in the moss that 

 covers the ground. As one approaches the 

 breeding-grounds, he will usually see one of the 

 birds fly by, uttering a low, plaintive whistle, and 

 presently notice the other running along the 

 ground, its plumage harmonizing so with the 

 moss as to be practically invisible when not in 

 motion. When flushed from the eggs, the parent 

 will usually run a few steps and then stand silent 

 and motionless; but sometimes it will shuffle 

 along the ground, its tail spread wide, and squeal 

 like a rabbit.
