Cerulean Warbler 455 
Distribution.—The breeding range of the Magnolia Warbler is limited 
to the Canadian zone, from Great Slave Lake and Newfoundland 
south to northern New York and along the Alleghanies to Maryland. 
In winter it resorts to southern Mexico and Central America as far 
as Panama. In Colorado it is merely a straggler and has only been 
taken during the spring migration. The following are the records : 
Near Denver with a flock of Audubons, on May 17th, 1873, by 
Henshaw ; near Denver again, by H. G. Smith, May 17th, 1888 ; 
near Fort Lyon, Bent co., by Captain Thorne, on May 17th, 1884 
(Cooke); near Springfield, Baca co., May 5th, 1905, by Warren; and 
near Holly, Prowers co., May 22nd, 1907, by H. G. Smith.
