42 i^OETH AMEEICAN WAEBLERS. 



during 1902 the bird appeared April 8 and departed May 5. The 

 average date of arrival for five j^ears at Columbia Falls, Mont., is 

 Ma}^ 5, and the earliest, April 30, 1897. 



646b. Helmintliopliila celata sordida Towns. Dusky Warbler. 



A resident form on the Santa Barbara Islands, California, known 

 also to have occurred on the mainland at Pasadena. 



647. Helmintliopliila peregrina ( Wils.)- Tennessee Warbler. 



Breeding range. — The Tennessee warbler is common in migration in 

 the Mississippi Valley, but is rather rare east of the Allegheny Moun- 

 tains. It occurs in summer in northern New England, and has also 

 been noted in northern New York and northeastern Minnesota. It 

 ranges north to the upper Yukon Valley, eastern British Columbia, 

 Nahanni River and Fort Wrigley in Mackenzie, Quebec, Labrador, and 

 the Gulf of St. Lawrence. An accidental occurrence has been noted in 

 California. During the summer of 1901 one of the parties of the 

 Biological Surve}" took two sets of eggs at Fort Smith, Mackenzie. 

 These eggs are among the first absolutely authentic specimens known 

 to science. 



Winter range.— Y)\\xm^ the winter this warbler is rather common in 

 northern Guatemala, and one of the parties of the Biological Surve}^ 

 found it at an elevation of 10,000 feet on the volcano of Santa Maria 

 where it was quite common, January- 21-28, 1896. It was taken b}" Sumi- 

 chrast at Sta. Efigenia, Oaxaca, Mexico, elanuary 3 and 11, 1869, and 

 was previousl}^ found by Boucard in the same State. It has twice been 

 noted at Jalapa, Vera Cruz. The only Yucatan record is from the 

 island of Cozumel. The only Honduras records are from' San Pedro 

 near the northwest coast, and the islands of Bonacca and Ruatan some- 

 what farther east. These records, taken in connection with the fact 

 that the Tennessee warbler is abundant in fall on the southeastern 

 coast of Nicaragua and occurs in Costa Rica and Panama, seem to 

 show that the bird migrates along the Atlantic side of Central America. 

 But for the present there is nothing to indicate that it passes inland to 

 the mountainous districts of Honduras or Nicaragua, or that there is 

 an}" southeastward migration along the mountains from Guatemala to 

 Costa Rica. 



In Colombia, South America, the Tennessee w^arbler has been taken 

 in the fall on the north coast at Bonda," and during the winter in the 

 mountains of the Santa Marta region at Minca (2,000 feet),^ Onaca 

 (2,500 feet),« Valparaiso (4,500-5,500 feet),« and Las Nubes (5,000 

 feet).^^ It is reported from Bucaramanga (3,000 f eet),^ and in the same
