TENNESSEE WARBLEE. 43 



vicinity at Herradura (4,000 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 t^'nited States 

 and Canada. 



SpriTig migration. — In spring migration the Tennessee warbler i.s 

 rarely found east of the Alleghenies, nor is it so common in the Mis- 

 sissippi Valley as during the fall migration. It is one of the late 

 migrants, reaching latitude 3?° 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 24, 1886, April 28, 1887, and April 27, 1888— average, April 27. 

 Northern records of average date of arrival are: Beaver, Pa., May 9; 

 central New York, May 13; eastern Massachusetts, May 14; Brook- 

 ville, Ind., May 4; Chicago, May 9; southern Wisconsin, May 16; 

 southern Michigan, May 15; Ottawa, May 16; Grinnell, Iowa, May 5, 

 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, May 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 4; Minca, Colombia, March 26; San Jose, Costa 

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

 latest at St. Louis, Mo., were May 21, 1884, May 22, 1885, May 15 

 1886, May 14, 1887, and May 20, 1888.
