498 Lake Maxinkuckee, Physical and Biological Survey 



On November 14, a female Mallard was caught in a steel-trap 

 set for muskrats. 



Four examples measured and weighed gave the following data : 



November 1, a female, weight 2 pounds, 5| ounces. 



November 1, a male, weight 2 pounds, 5^ ounces. 



December 2, a male, 22^ inches long, weight 2 pounds, 7 ounces. 



December 2, a female, 19^ inches long, weight 2 pounds, 2^ 

 ounces. 



The Mallard is primarily a vegetable feeder. The stomach of 

 one examined November 30 contained bits of a fine-leaved Pota- 

 mogeton; two examined November 1 contained stolons of wild 

 celery. Others examined contained seeds of various plants, par- 

 ticularly smartweed. 



16. BLACK MALLARD 



ANAS RUBRIPES Brewster 



The Black Mallard or Black Duck is not common. Seven were 

 seen September 18, 1899, several on November 3 and 4, and 3 or 

 4 on Lost Lake, November 15, 1900, and a female was shot De- 

 cember 7, 1900. A fine flock was seen in a marsh near the tama- 

 rack swamp early in the spring of 1901, and several were seen 

 flying over Long Point, October 23, 1906. It is not known to 

 breed here. 



17. GADWALL 



CHAULELASMUS STREPERUS (Linnzeus) 



The Gadwall or Gray Duck is rare at Maxinkuckee. Our notes 

 contain no definite records of its occurrence, but it undoubtedly 

 does occur here occasionally as a migrant. 



18. WIDGEON; BALDPATE 



MARECA AMERICANA (Gmelin) 



Apparently rare; several seen in the lake near Farrar's, April 

 7, 1885 ; none noted recently. A spring and fall migrant. 



19. GREEN- WINGED TEAL 



NETTION CAROLINENSE (Gmelin) 



A spring and fall migrant, apparently not common. One ob- 

 tained October 31, 1902, and several seen two days later; a fine 

 plumaged male shot October 22, 1907 ; length 13 inches, weight 11 

 ounces; another (a female) shot October 25, 1907.
