32 WORTH AMERICAN WARBLERS. 



1890. At the Tortugas, Fla., a male was taken March 26, and a 

 female April 9." During this year the birds were observed for the 

 first time on the mainland of Florida. Spring migrants were found by 

 Brewster and Chapman to be not uncommon on the Suwanee River.* 

 The first male was taken March 12; the first female, March 15. The 

 date of greatest abundance was March 23, when more than 30 individ- 

 uals were identified. The next day was the last on which they were 

 seen. The country traversed changed in character on that date and 

 probably became unsuited to the species. None of the 46 specimens 

 secured would probably have bred for several weeks. 



1893. In March Arthur H. Wayne obtained about 50 specimens on 

 the Suwanee River, Florida.*^ 



1894. In the spring 8 specimens were taken in Jefl'erson County, 

 Fla., along the Wacissa and Ancilla rivers.'' 



Fall migration. — ^^1888. The following captures and observations 

 were made at Key West* by Mr. Atkins: July 26, 4 taken, 20 more 

 noted; July 28, 3 taken, 2 more noted; July 29, 2 taken, 2 more noted; 

 August 6, 2 taken, about 22 more noted; August 8, 5 taken, about 7 

 more noted; August 9, 2 taken, about 6 more noted; September 5, 1 

 (the last) noted. 



1889. Important records were again made at Key West^ by Mr. 

 Atkins, as follows: July 17, 1 male and 1 female noted (the earliest 

 arrivals from the north); July 23, 3 noted; July 31, 3 noted; August 

 4, about a dozen noted; August 4-25, passing birds noted regularly, 

 usually in small numbers, but reaching the maximum of 25 to 30 on 

 August 8. None were observed after August 25. Mr. Atkins secured 

 about 40 specimens during the time of passage. 



1900. One taken at Tallahassee, Fla. , August 4, and one in Madison 

 County, La., in August. 



641. Helminthopliila pinus (Linn. ). Blue- winged Warbler. 



Breeding range. — The summer range of the blue-winged warbler is 

 rather restricted, and its limits correspond quite closely with the Car- 

 olinian life zone. The center of abundance in the breeding season is 

 central and southern Ohio, Indiana, Illinois, northern Kentucky, north- 

 ern Missouri, and southern Iowa. It thus includes the lower Ohio 

 Valley up to 1,000 feet altitude, and the valley of the Missouri, through 

 the States of Missouri and Kansas, to the same altitude in southeastern 

 Nebraska. To the eastward the bird avoids the mountains entireh', 

 even in migration, but breeds rarely and locally in some of the lower 

 parts of southern Pennsylvania and Maryland (one record). There is 

 a local colony, where it is almost common, that includes southeastern
