196 Phillips, Migration of Anatidac in Massachusetts. [April 



Canada Goose (Branta canadensis). As I have noted in a 

 previous paper (Auk, July, 1910), geese are much less common here 

 than at Chebacco Lake on Cape Ann, or rather at the base of it. 

 There is a fly-way across the north end of Wenham Lake between 

 Dodge's and Burnham's Hills, where far more geese pass than at 

 the blind, from which point this fly-way cannot be seen. One 

 hundred and eighteen geese figure in the totals. On a number of 

 years, as will be seen by the table, the camp was closed too early 

 to take advantage of the geese. 



Cormorant (Phalaerocora.v carlo). Occasionally these birds 

 have dropped into the lake, when, after a few dives, they usually 

 go out of their own accord. Seven specimens have been taken, 

 and a few others noted on the pond. Flocks in migration are 

 common. 



American Merganser (Mcrgus americanus). A moderately 

 common visitor to the lake after November 1. Twenty-three 

 specimens have been taken, but among these only two fine males. 

 On December 7, 1902, I have a record of the weights of these two 

 males; 3 lbs. 15 oz. and 3 lbs. 7 oz. It is probable that the migra- 

 tion of the males is much later than that of the females. 



Red-breasted Merganser (3Icrgus scrrator). About as com- 

 mon as the American Merganser, 29 having been taken. Adult 

 males very rarely seen, as in the foregoing species. Neither of 

 these birds take kindly to live decoys, and approach the shore 

 only in rather deep water. 



Hooded Merganser (Lophodytcs cucnUatus). This bird has 

 occurred in nine of the ten years, and is by far the commonest 

 merganser seen about the pond. Adult males are again exceedingly 

 rare. Out of 44 birds taken, I have only one really fine male in 

 my collection, while I can recall only one or two others nearly 

 approaching adult plumage. The fine male was taken on Novem- 

 ber 2, 1908. Unlike the preceding two species, this "wood 

 sheldrake" is glad to associate with live decoys, and usually swims 

 quickly among them if he alights near by. Of late years we have 

 allowed them to go unmolested. 



Holbcell's Grebe (Coh/mbus holbcrlli). Represented by three 

 specimens only, taken Oct. 27, 1903, Oct. 24, 1904, and Nov. 13, 

 1902.
