OIDEMIA AMERICANA Swainson 



AMERICAN SCOTER 



HABITS 



This is the least known and the rarest of the three species of 

 scoters or " coots " which migrate up and down our coasts on both 

 sides of the continent ; it is also the hardest of the three to identify 

 in life, as it has no distinctive marks visible at a distance; hence 

 it is commonly referred to by nearly all observers in connection with 

 the other tw^o, and it is very difficult to separate much that is appli- 

 cable to this species alone. This group as a whole seems to be 

 rather unpopular among naturalists, as it is among sportsmen ; con- 

 sequently comparatively little effort has been devoted to the study of 

 its habits. 



Spring. — The spring migration of the American scoter, on the 

 Atlantic coast, is eastward and northward along the seacoast; I can 

 find no evidence of an overland flight to the interior, which is so 

 conspicuous in the white-Avinged scoter. During April and the early 

 pai't of ^Tay huge numbers may be seen migrating eastward through 

 \"incyard Sound and around Cape Cod. On the south coast of 

 Labrador we saw them flying eastward during the latter part of May 

 imd the first half of June. While migrating the three species usually
