LAND BIRDS. 583 
in 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 May 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, but this mistake would never occur had the observer ever handled 
an actual specimen of the latter bird.
