Genus GLAUCIONETTA Stejn. 



55-151-(725). (Jlaucionetta clausula americana (Bonap.). American Golden-eye; 

 Golden-eye; Whistler; Garrot. 



" Common from the north, late in November, and often remains all winter on open 

 spots of swift running rivers, dives at the flash of a gun, and will escape shot at thirty 

 feet to my certain knowledge'' (Dr. M. Gibbs); " throughout the state" (A. H. Boies); 

 reported from Kent Co.; migrant; " Dr. Brayton gives this as a winter resident on Lake 

 Mich." (Amos W. Butler); " winter resident on Lake Michigan and open inland lakes" 

 (Prof. Ludwig Kumlein); " Keweenaw Point" (Kneeland); " common on the rapids of the 

 St. Mary's River all winter" (C. S. Osborn); "this bird is taken at Pine Lake, is a fine 

 game duck and is so quick to dive that it is difficuit to shoot it on the water" (A. H. 

 Whitehead). There are several of these ducks in the collection of Mr. Levi Broas, of 

 Belding, Mich., taken by him in that locality. I think this a common species all 

 through the Southern Peninsula.
