The Migration Route of Kirtland's Warbler. By Chas. C. Adams^ 

 Bull Mich. Ornith. Club, Vol. V, pp. 14-21, March, 1904. 



This second contribution to the life history of kirtlandi, an at- 

 tempt to determine its route of travel from the Bermudas, its winter 

 home, to its known breeding range in Michigan, is well timed. It is 

 accompanied by a like study of the migration route of the Prothono- 

 tary Warbler, both being illustrated by maps. This discussion is neces- 

 sarily limited to the known occurrences of the bird, and from the data 

 at hand its route of migration seems to be from its winter home west- 

 ward to the Mississippi river, thence north to the mouth of the Ohio, 

 one branch continuing up the Mississippi to St. Paul, on its course 

 giving off branches at the Illinois river, the birds reaching southern 

 Michigan by skirting the southern end of Lake Michigan, and another 

 branch entering northern Illinois. The Ohio offshoot again divides, 

 one course being up the Ohio to Cincinnati, the other up the Wabash 

 to northern Indiana and northern Ohio and eastern Michigan, there 

 following the course of Lake Huron to Mackinac. The course thus 

 pursued almost exactly corresponds to the post-glacial drainage of the 

 regions covered. No doubt the birds pass further up the Ohio and 

 finally cross to Lake Erie by one of the main tributaries, possibly the 

 Muskingum or Scioto. Now that this bird has been brought so promi- 

 nently before us there should be additional records of migrating birds.

Unpublished Letters of John James Audubon and Spencer F. 

 Baird. By Rutbven Deane. From "The Auk," Vol. XXI, No. 2, 

 April, 1904. 



This paper consists of a letter from Baird to Audubon, and Audu- 

 bon's reply, concerning Audubon's proposed western trip, and a recom- 

 mendation of Baird to a position in the "National Institute," by 

 Audubon. These letters give us a hint of the esteem in which Audu- 

 bon, then sixty-two years old, held Baird, then but nineteen. L. J.
