of the data attached to these birds fixes with considerable cer- 

 tainty the winter distribution of this species and throws some 

 light on its routes of migration and probable breeding range. 



Thus during the winter Kirtland's Warbler apparently ranges 

 throughout the Bahamas, having been found from Caicos to 

 Abaco, though it has not as yet been recorded from Inagua. 

 Its northward migration begins in April, South Carolina being 

 reached toward the end of the month, either by direct flight from 

 the Bahamas, or, what is more probable, by advancing northward 

 along the Southeast Atlantic Coast (St. Helena, April 29, 

 Worthington) . 



This is the most northern, spring cis-Alleghanian record, the 

 migratory route of the species now leading it northwestward into 

 the Mississippi Valley. 



It is reported from Missouri, May 8 (St. Louis, Widmann) ; 

 from Illinois, May 7 (Glen Ellyn, Gault) ; from Indiana, May 

 4 and 7 (Wabash, Wallace) ; from Ohio, May 12 and 13 (Cleve- 

 land, Pease and Chubb ; four other Ohio specimens without exact 

 date) ; from Minnesota, May 13 (Minneapolis, Guilford), and 

 from Michigan, May 11 (Battle Creek, Green), May 15, 16 (Ann 

 Arbor, Covert; also one specimen about May i, Knapp) , and 

 May 21 (Mackinac, Marshall). This last is not only the latest 

 spring record but also the most northern record we have of the 

 species. The specimen on which it is based was killed by 

 striking the lighthouse situated at the Straits of Mackinac and, 

 as I have before suggested, was doubtless en route to a more 

 northern breeding ground in the Hudson Bay region. 



In the fall we have only two records for Kirtland's Warbler 

 (Ft. Myer, Va., Sept. 25, Palmer, and Chester, So. Car., Oct. 

 II, Loomis), suggesting that the species returns to its winter 

 quarters over much the same route it selects for its northwestward 

 journey in spring. 



Few of the ornithologists who have been so fortunate as to 

 secure specimens of this rare Warbler have given us any account 

 of its habits. Mr. Cory, however, states of a specimen he 

 secured on Andros Island : " Its actions much resembled those 

 of D. coronata, and it seemed to prefer thick brush." Mr. Wid- 

 mann compares it to D. palmarum and says that it has the
