due either to the destruction of its natural food by carp or to a change 

 in its route ot migration. The latter reason receives credence among 

 sportsmen. I saw three on March 18 and a flock of 25 on November 23. 



Lesser Scaup {Marila affinis). — Common in spring, particularly on 

 the Illinois River. A few were also encountered on some of the larger 

 sloughs, but their center of abundance was near the docks at Brown- 

 ing, where they obtained the offal thrown out from the fish market. 

 In fall they were decidedly rare. Three females were noted at one trap 

 on October 16, one was seen on the 21st and another on November 16. 



Ring-necked Duck {Marila collaris). — Plentiful in March but not 

 seen at all in the fall. On March 18, I examined a "raft" composed 

 mainly of this species, which I estimated to contain 3,000 birds. They 

 are found on the sloughs more frequently than the lesser scaup, result- 

 ing in their local name of "timber blackjack." 



Golden-eye {Glaucionetta c. am eric an a). — Seen on three different 

 days, all in spring, two on March 2, three on the 3d, and two on the 19th. 



Buftte-head {Charitonetta albeola). — A flock of ten "butter-balls" 

 flew over the club house on March 3, the only time this species was 

 observed there. 



Canada Goose (Branta c. canadensis). — Geese were heard on October 

 18, and on the 20th three flocks were observed flying over, the largest 

 numbering about 75 birds. 



Snow Goose {Chen h. hy perb ore us). — Snow geese are almost unknown 

 in this vicinity so I was much surprised to learn of a flock (estimated 

 at 150 birds) that was observed on Crane Lake on October 27.
