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 Thome, 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.
