TENNESSEE WARBLER. 43 



vicinit}^ at Herradura (1,000 feet)/' One of the highest recorded alti- 

 tudes is Concordia (6,000 feet) ^ in Antioquia. Other records in South 

 America are at Santa Marta, Colombia,^' and at Caracas, Venezuela/^ 

 One of Boucard's specimens in the National Museum is marked 

 "Merida, Venezuela, 1889." The winter records are made almost 

 entirely in the mountains, but not nearly at such high altitudes as one 

 might expect from the boreal habit of the bird in the United States 

 and Canada. 



Sjjring migratlo7i. — In spring migration the Tennessee warbler is 

 rarei}^ found east of the Alleghenies, nor is it so common in the Mis- 

 sissippi Valle}^ as during the fall migration. It is one of the late 

 migrants, reaching latitude 37° about April 27, as shown by the fol- 

 lowing dates of arrival: Rising Fawn, Ga., April 26, 1885; southwest- 

 ern Missouri, April 27, 1874; Acton, Ky., April 29, 1901; and St. 

 Louis, April 25, 1882, April 25, 1883, April 29, 1884, April 28, 1885, 

 April 21, 1886, April 28, 1887, and April 27, 1888— average, April 27. 

 Northern records of average date of arrival are: Beaver, Pa., Ma}^ 9; 

 central New York, i\Iay 13; eastern Massachusetts, May 11; Brook- 

 ville, Ind., May 1; Chicago, May 9; southern Wisconsin, May 16; 

 southern Michigan, May 15; Ottawa, Ma}" 16; Grinnell, Iowa, Maj^S, 

 and Lanesboro, Minn., May 11. 



The Biological Survey has received no notes from the South Atlan- 

 tic States on the spring migration of the Tennessee warbler, nor from 

 Alabama, Mississippi, or Louisiana, though two birds were seen in 

 April in Cuba^ and some were taken on the island of Grand Cayman,-^ 

 and the species has been noted several times in spring at Pensacola, 

 Fla. The few notes from farther west indicate the arrival of the bird 

 at Corpus Christi, Tex., April 3, 1891; Bee County, Tex., April 18, 

 1887; San Antonio, Tex., April 21, 1891; Manhattan, Kans., May 2, 

 1893; Lincoln, Nebr., May 7; Aweme, Manitoba, May 13, 1903; Fort 

 Simpson, Mackenzie, Ma}'^ 26, 1860, and Caribou, British Columbia, 

 May 22, 1901. Six records have been made of the occurrence of this 

 species in Colorado, where during the early days of May, at the 

 western limit of its range, it is a rare migrant along the base of the 

 eastern foothills. 



The latest dates of departure south of the United States are at Valpa- 

 raiso, Colombia, April 1; Minca, Colombia, March 2Q\ San Jose, Costa 

 Rica, March 6, 1889; and Jalapa, Vera Cruz, April 18, 1897. The 

 latest at St. Louis, Mo., were May 21, 1881, May 22, 1885, May 15, 

 1886, May 11, 1887, and May 20, 1888.
