 Island.

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 ); 

 observed once in January when the river was free of ice, when several were seen on 

 Saginaw Bay. common in spring, rarely seen in summer, but old and young are abund- 

 ant in fall, formerly bred on Heisterman's and other islands on Saginaw Bay, possibly 

 breeds now on Charity Islands" (N. A. Eddy); "common at St. Joseph in spring and 

 autumn, many remaining through the winter. They are often seen in flocks. They 

 follow the tugs for refuse, and are very common at Marquette " ( O. B. Warren ); " com- 

 mon in spring, summer and fall, and are seen occasionally in winter, nest abundantly 

 on Thunder Bay Island, off Alpena" ( W. A. Oldlield); "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

 all the great lakes. C S. Osborn writes me that Gulls deposit barrels of eggs on the 

 rocky islands of Georgian Bay. These eggs are gathered by thousands and eaten by 

 fishermen, or used in manufacturing eggine or egg albumen. 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.
