19-51a-(773). Larus arg-entatus smitlisonianus Coues. American Herring Gull; 

 Smithsonian Gull. 

 Very abundant; throughout the state; migrant and winter resident; breeds; "nests 

 abundantly on Isle Royal, Michigan" (Frank S. Daggett in O. and O., Vol. XV, p. 99); 

 "common in -January on Saginaw Bay " (N. A. Eddy in O. and O., Vol. IX, p. 5); " nests 

 very extensively on hummocks on the ground at Gull Island, east of Escanaba," (L. W. 

 Watkins); "breeds at Mackinac Island, and is common on the Grand river at Grand 

 Rapids" (S. E. White); '■common on Lake Erie" (Jerome Trombley); "Keweenaw 

 Point" (Kneeland). This and Boneparte's Gull are ofter seen as far inland as Lansing. 

 They are common along all the great lakes. C. S. Osborn writes me that Gulls deposit 

 barrels of eggs on the rocky island of Georgian Bay. These eggs are gathered by

 The number is simply marvelous. See interesting article by Frank S. Daggett in O. 

 and O., Vol XV, 1890, p. 99. It is stated that some of the very numerous nests at Isle 

 Royale were on the unstable icebergs.
