LAND BIRDS. 583 



irl winter to Cuba and northern South America. Breeds throughout its 

 United States range. 



The right of the Worm-eating Warbler to a place in the Michigan list 

 seems to rest largely on the record of A. B. Covert, who states that he took 

 a male at Ann Arbor, Washtenaw county, May 21, 1878. The specimen, 

 however, has been lost sight of. The species is mentioned in Stockwell's 

 list in Forest & Stream as a rare visitant to the southern counties (F. and 

 S., VIII, 261), and it occurs in Cook's list of 1893 on the authority of 

 Major Boies, of Hudson, Lenawee county. Major Boies, however, appears 

 never to have taken a specimen and possibly was mistaken in recording 

 it for Lenawee county. Dr. Gibbs has never found it in Kalamazoo county, 

 but notes D. D. Hughes' statement that one was taken in June 1868, by 

 a Mr. Hurd. That most careful observer, Jerome Trombley, has failed 

 to note it at Petersburg, Monroe county. 



Butler states that he does not know of its occurrence in northeastern 

 Indiana beyond the Wabash river, but says that it has been taken on the 

 shore of Lake Michigan at Waukegan, Illinois, above Chicago, May 21, 

 1876 (Birds of Indiana, 1897, p. 1027). Kumlien and Hollister also record 

 a single specimen taken at Lake Koshkonong, southern Wisconsin, in May 

 1873, and another in ]\Iay 1877. 



The Worm-eating Warbler has been reported from time to time from 

 various parts of Michigan, even from the Upper Peninsula, by observers 

 who were unquestionably honest, but mistaken. The bird is a southern 

 form which enters the state, if at all, only at long intervals and in small 

 numbers. Undoubtedly females and immature specimens of the Black 

 and White Warbler have been occasionally mistaken for the Worm-eating 

 Warbler, l^ut this mistake would never occur had the observer evei- handled 

 an actual specimen of the latter bird.
