Remarks. There is no excuse for confusing the Canvasback with the 

 Redhead as will be seen by reference to plate 16. The Canvasback drake 

 is much lighter in color of the body, the neck is a darker red and the face 

 smoky. He is also of longer build than the Redhead. The females and 

 young of the two species are more similar in coloration, and the best mark 

 is the profile of the bill and forehead, which rises gradually from the nostril 

 to the crown of the head in the Canvasback, but shows a decided "break" 

 at the feather-line in the Redhead. 



Throughout the Hudson-Champlain valley and the coastal region of 

 New York the Canvasback is a rare migrant and is not a common duck 

 in any portion of the State. Occasionally, however, it has visited the 

 central lakes, especially Canandaigua, Keuka, Cayuga, and Seneca, in large 

 numbers. The winters of 1897-98 and the three following winters were 

 remarkable for the large flocks of canvasbacks which appeared about 

 the ist of December on these waters and remained until early in March. 

 On Canandaigua lake a flock of nearly 1000 canvasbacks passed a large 

 X^art of the winter, and on Keuka lake flocks of 200 birds were frequently 

 seen. In February 1899 many of these ducks were killed on Canandaigua 

 lake about the air holes which remained open. Most of those killed were 

 in poor flesh and some were picked up on the ice in a starving condition. 

 During the past few years there have been fewer canvasbacks in winter, 

 but they occur in limited numbers as regular migrants from the ist to the 

 20th of April and from October 20th to Noyember 15th. On Long Island 

 Mr Dutcher's Notes show it to be a rare migrant from February 14th to 

 April 6th and from October 12th to December nth.
