Prof. Baird says The American Redhead duck is quite distinct from the 

 Pochard of Europe, though resembling it very closely Audubon considered it 

 to be identical. The Redhead duck is pretty generally distributed throughout 

 North America, breeding in high latitudes down to 44 degrees and in ' the 

 winter going as far south as Mexico. Richardson says that this species breeds 

 in all parts of the fur countries from the 50th parallel to their most northern 

 limits. It is common in autumn on Chesapeake Bay and other points along 

 the Atlantic coast, and is here often found associating with the Canvasback which 

 it so closely resembles, in fact in the New York markets it is frequently sold as 

 the genuine Canvasback and indeed while feeding on the wild celery its flesh 

 is not much inferior to that of that famous duck. Formerly the redhead was 

 quite a plentiful species in Ontario, but of late years its numbers appear to be 

 diminishing rapidly, in fact at some stations where large numbers of them used 

 to be shot, not a single specimen has been taken during the last two shooting 

 seasons. This fact may be largely due to the legal existence of spring shooting 

 in some of the neighboring states and the netting of them in the southern 

 states. Like the Bluebill they decoy well and are thu=! tolerably easily led into 

 traps baited with curn of which they are very fond. The Redhead reaches 

 Ontario early in April and returns late in October and November staying till the 

 ice forms and in some instances on our open lakes all winter. The female lays 

 from 8 to 10 eggs of a grayish white colour.
