During his stay in this summer home of the Kirtland Warblers 

 in Crawford and Oscoda Counties, Mr. Wood saw and heard 

 sixteen birds, and in ten days he secured two pairs of Warblers 

 with their nests, seven young and one egg ; also four adult males, 

 making fifteen birds in all. Mr. Wood also says that he is in- 

 clined to think "the Au Sable River is the southern boundary of 

 their breeding area and that this area extends over the greater 

 part of the Canadian zone of Michigan, Wisconsin and perhaps 

 Minnesota. They will probably be found breeding in favorable 

 localities in the Upper Peninsula of Michigan, but I should not 

 expect them north of Lake Superior." In spite of Mr. Wood's 

 success Kirtland's Warbler must still be considered a very rare 

 bird, and it probably breeds only in small colonies, and then only 

 among the jack pines in favorable localities. 



Mr. Robert Ridgway gives the following as the geographical 

 range of Kirtland's Warbler : "Eastern United States and more 

 southern British Provinces, chiefly west of the Alleghanies; 

 very irregularly distributed and breeding range unknown; has 

 been found in the following states: Ohio, Indiana, Illinois, Mis- 

 souri, Minnesota, Wisconsin, Michigan, Virginia, South Carolina ; 

 also in Ontario. Winters in the Bahamas."

The Pine Warbler is a rather rare migrant, arriving in the 

 spring from the middle of April to the last of May, and returning 

 in the fall from the twentieth of September to the twelfth of 

 October. Mr. E. W. Nelson considers it a common migrant 

 and says: "The first of July, 1874, I found a large number of 

 these birds with young just old enough to follow their parents, 

 in the 'Pinery/ and presume they nest there regularly." Dr. 

 A. W. Brayton says:* "Nelson found both young and old in 

 the pine barrens, Lake County, where they undoubtedly breed 

 regularly." 



The range of the Pine Warbler covers North America east 

 of the Great Plains ; and from New Brunswick, Ontario and
