is undoubtedly the Little Bluebill (Marila affinis) , and the second 

 in abundance is the Canvas-back (Marila valisineria) . Following 

 these come the Redhead (Marila americana) , the Mallard (Anas 

 platyrhynchos) , the American Merganser (Mergus americanus) , 

 the Ruddy Duck (ErismaUira jamaicensis) and the Butterball 

 (Charitonetta albeola) . The remaining fourteen species are each 

 less common. 



The state law regarding hunting water-birds is not as well 

 obeyed at Maxinkuckee as it should be. The most serious offend- 

 ers are those who have launches or motor-boats of one sort or 

 another. Not all those having such boats violate the law, but sev- 

 eral of them do. They not only chase or pursue the ducks with 

 their launches, but do it after sundown, and even without any sort 

 of hunting license. 



The Lake Maxinkuckee Association should have their patrol- 

 man made a special game warden and then see to it that he be 

 active and fearless in enforcing the law against all pot-hunters. 



In nomenclature and sequence of species we have followed the 

 third (revised) edition of the Check-List of North American Birds, 

 issued by the American Ornithologists' Union in 1910. 



List of Species 

 1. holbcell's grebe 



COLYMBUS HOLBCELLI (Reinhardt) 



The only definite record we have of this species was made Oc- 

 tober 12, 1913, when a single individual was observed in the lake 

 150 to 200 yards or more east of Long Point. Its larger size, long 

 slender neck, and white color at once attracted our attention as in- 

 dicating a species different from the horned grebe or pied-billed 

 grebe. Considerable time was devoted to observing it. It was evi- 

 dently feeding, as it dived very frequently, remaining under sev- 

 eral seconds and usually coming up not far from where it went 

 under. Occasionally it would stand up in the water and flap its 

 wings. 



This species of grebe feeds on small mollusks, crustaceans and 

 small fishes. 



2. HORNED GREBE 



COLYMBUS AURITUS Linnaeus 



This little grebe is not common at Lake Maxinkuckee, but a 

 few may be seen in the spring and again in the fall. We have 

 observed it in April and June ; also in October, November, Decem-
