Fig. yi — Red-breasted Merganser, with Outline of Bill from above. 



This is the commonest one of the three, especially 

 along the coast. The figure represents the bill of natural 

 size, and shows the sub-basal position of the nostrils, 

 which are more median in M. merganser. The nest 

 IS placed on the ground; carefully concealed in rank 

 herbage ; it is neatly constructed of mosses, lichens, hay 

 and seaweeds, and warmly lined with down from the 

 parent's breast. The eggs are some nine or ten in 

 number, of a fine creamy buff color, oval or ellipsoidal, 

 measuring about 2.50 X 1.65.
