The Scaup-Duck arrives on our coasts in the end of Octo- 
ber, and continues to increase until the middle of winter. In 
the estuaries and along the flat shores, it is met with plenti- 
fully, often in very large flocks ; but it also sometimes betakes 
itself to fresh water. Its food consists chiefly of mollusca, 
which it obtains by diving. Its flight is moderately quick, 
generally low. In the end of March and beginning of April 
it disappears from our coasts. The species occurs equally in 
North America.
