BLUE-WINGED WARBLER. 33 



New York and adjoining parts of New Jersey and Connecticut. The 

 bird occurs in western New York and through southern Michigan to 

 southern Minnesota. In the Austroriparian zone it breeds very rarely, 

 as but three recorded instances are known: in the Creek Nation, Indian 

 Territory, on the St. Francis Kiver, in extreme southeastern Missouri, 

 and on the coast of Georgia near the mouth of the Altamaha River. 



Migration range. — Through most of the Austroriparian region of the 

 Southern States the species is a migrant, but is nowhere recorded as 

 even tolerably common. Along the south Atlantic coast it occurs as a 

 rare migrant in spring and fall, and all the records come from below 

 the 500-foot contour. There are single records from South Carolina 

 and Georgia, a few from Alabama and Louisiana, and quite a number 

 from eastern Texas, even to the Kio Grande. 



Winter range. — In winter, so far as noted, the blue-winged warbler 

 is quite widely distributed, but is nowhere common. A single speci- 

 men was taken at Metlaltoyuca, Puebla, February 22, 1898, by one of 

 the parties of the Biological Survey. On four other occasions the spe- 

 cies has been taken in Mexico, in each instance in the State of Vera 

 Cruz. Its special winter home seems to be in Guatemala, where it has 

 been found from near sea level to an elevation of 4,000 feet. The 

 only locality on the Pacific slope at which it has been recorded is Retal- 

 huleu in southwestern Guatemala, at about 1,000 feet altitude. On 

 the mainland east of Guatemala there are five records of its occur- 

 rence. An individual was taken by Gaumer in northern Yucatan," and 

 another by Dyson in Honduras;* one was seen February 8, 1892, and 

 one January 17, 1893, along the coast of southeastern Nicaragua;" and 

 one was taken March 21, 1899, at Chirua, Colombia,"^ at 7,000 feet 

 altitude — the only record of the occurrence of this species in South 

 America. In the West Indies, excepting the specimen taken on the 

 island of Abaco, Bahamas, April 7,^ its presence has never been 

 recorded. 



Spring migration. — South of the United States no notes of blue- 

 winged warblers in migration have been recorded except in the single 

 instance of an individual seen April 7, 1897, at Jalapa, Vera Cruz;-'' 

 but northward migi*ation must commence in March, as the earliest 

 recorded arrival from the South at New Orleans is March 22, 1898. 

 Spring records from the mainland of Florida are lacking, but three 

 individuals were noted on the Dry Tortugas, March 23, 1890, and
