 (Griscom). A female seen May 12, 1918 (J. M. Johnson) was

RED-BREASTED MERGANSER (Mergus serrator) 

 An abundant migrant and common winter resident on 

 Long Island, but of very rare occurrence on the inland waters 

 of our area. Mearns and Fisher regarded this species as very 

 common on the Hudson fifty years ago, but this is most 

 emphatically not the case today, and the greatest care should 

 be taken by observers in identifying this species away from 

 salt water. The drakes of the two Mergansers are unmistak- 

 able, but females and young, in this species, have lighter 

 colored heads, and there is a gradual transition from the color 

 of the head to the whitish throat and underparts, whereas in 

 the American Merganser this change is abrupt. These 

 characters, however, are not easy to make out, and require 

 very close range or direct comparison. 



Long Island. Common winter resident, abundant transient? 

 barren birds occasional in mid-summer. September 15 to June 15- 

 ORIENT. Usually common in winter, always common in 

 spring and fall. Rare in summer. September 20, 1919 to 

 June 11, 1911. Average arrival, October 15; average depar- 

 ture, May 25.
