112 ISrOETH AMERICAN WARBLERS.

 These records show what numbers of the bird must pass in the fall 

 through New England. 



The Connecticut warbler has been seen at Chicago as late as Sep- 

 tember 17, 1894; Portland, Conn., October 1, 1894; Englewood, N. J.,

679. Geothlypis pliiladelpliia (Wils. ). Mourning .Varbler. 



Breeding range. — The mourning warbler is most common in sum- 

 mer in northern Minnesota and the valley of the Red River of the 

 North in North Dakota and Manitoba. It occurs rarely in eastern 

 Assiniboia. It is found breeding, but is less common in Michigan, 

 central Ontario, northern New York, Yermont, and New Hampshire, 

 and in the Catskills and the mountains of Berkshire County, Mass. ; 

 also in Maine, where it seems to be quite common locally in the north 

 eastern part, and east to New Brunswick, Prince Edward Island, and 

 Nova Scotia. It also breeds in some of the mountains of Pennsylvania 

 and West Virginia. 



Migration range. — With the exception of a probably accidental 

 occurrence in South Carolina, it has not been recorded outside the 

 mountains at any time of the 3^ear in the Atlantic and Gulf States, 

 from North Carolina to Mississippi. It is a rare migrant in Louisiana, 

 but is fairly common in migration in Texas. Its distribution in the 

 United States is therefore fan-shaped. Touching the Gulf of Mexico 

 along the coast of Louisiana and Texas, a distance of 600 miles, the 

 lines of migration extend north to Manitoba and northeast along the 

 west side of the Alleghenies to New Brunswick, Nova Scotia, and the 

 Magdalen Islands. The east and west extension of the breeding ground 

 is nearh^ 2,000 miles. 



Winter range. — The distribution of the mourning warbler in winter 

 is rather less extended than in summer. A single specimen taken on 

 the southeast coast of Nicaragua," February 4, 1892, constitutes the 

 only record for this country. The bird is a not uncommon winter 

 resident in Costa Rica, Panama, and Colombia, and there are a few 

 records of its occurrence in Ecuador. Since the summer home of the 

 species is principally in the Canadian zone, with but few individuals 

 nesting in the AUeghenian, one would naturally expect it to seek the 

 mountains in winter; and it is interesting to note that all the winter
