FIG. 71. YOUNG MALE SURF DUCK, WITH OUTLINE OF BILL FROM BELOW. 



A migrant and winter visitant, in numbers interme- 

 diate between those of the other species of the genus, 

 the circumstances of its appearance, however, being the 

 same. Dr. Brewer notes them all as " migratory " only, 

 ignoring their winter residence. Any of them may be 

 casually found during the whole year ; but none appear 

 to be properly estimable as summer residents or breed- 

 ers in New England.
