This beautiful bird is pretty common on our shores ; and 

 it is much pursued, both for the beauty of its plumage 

 and for the excellence of its flesh. It breeds in the most 

 northern portions of the continent, where, Nuttall says, " it 

 lays eight or nine eggs of a greenish-blue color." It is seen 

 in most abundance in the autumn on our coast, where it 

 appears by the 10th of September, and remains until the 

 last week in October. Wilson says it is a shy and cau- 

 tious bird, feeds in the mud flats, and shallow fresh-water 

 marshes ; but rarely resides on the seacoast. It seldom 

 dives, is very noisy, and has a kind of chattering note. 

 When wounded, they will sometimes dive, and, coming up, 

 conceal themselves under the bow of the boat, moving round 

 as it moves ; are vigilant in giving the alarm on the approach
