CANADIAN WARBLER. 181 



but has also been taken in migration at 800 feet in Guatemala and at 

 sea level in Panama. It has been recorded in winter in Guatemala, 

 but most of the birds go much farther south. Even in Costa Rica 

 Cherrie saw none in winter, though thev were abundant there in fall 

 migration. 



Spring 'migration. — The Canadian warbler is one of the late migrants. 

 The few records of spring arrival of the species that have been gath- 

 ered in the southern United States are: Southern Texas, May 2^ 

 1877; Corpus Christi, Tex., Ma}^ 1, 1900; Victoria County, Tex., 

 April 26, 1887; San Antonio, Tex., May 4, 1881; Shellmound, Miss., 

 April 15, 1892; Hickman, Ky., April 21, 1888; Lexington, Ky., April 

 29, 1899; St. Louis, May \i, 1883, May 11, 1884, May 11, 1885, May 

 11, 1886, May 8, 1887, April 28, 1888 (next seen May 5; bulk pres- 

 ent from May 11 to May 19; last noted in various years May 19 to 

 May 22); Rising Fawn, Ga., April 26, 1885; Highlands, N. C. April 

 29,1886; Asheville, N. C, May 4, 1891. As the Canadian warbler 

 passes north it has been noted on the average at Washington May 9; 

 Beaver, Pa., Ma}^ 5; Philadelphia, Englewood, N. J., and Lockport, 

 N. Y., May 15; in eastern Massachusetts, May 11; southern New 

 Hampshire, May 18; southern Maine, May 19; and southern New 

 Brunsvvick, May 28. 



Rather incongruous dates are reported from west of the Alleghenies. 

 The average date of arrival for five 3^ears near Waterloo, Ind., is May 

 2, and for nine years at Listowel, Ontario, May 1, while not far dis- 

 tant the date of arrival at Chicago is May 15; Petersburg, Mich., 

 May 13; Parry Sound district, Ontario, Maj^ 21, and Ottawa, Ma}^ 

 21. The first migrant appears on the average at Lanesboro, Minn., 

 May 19. One w^as seen at Aweme, Manitoba, May 20, 1899, and one 

 at Edmonton, Alberta, May 29, 1897. 



In northern Peru in 1878 a specimen was shot as late in the spring- 

 as March 28, and in central Ecuador in April, 1899, both males and 

 females were taken. A belated migrant was taken April 28, 1893, at 

 Chalchicomula, Puebla, Mexico, at 8,200 feet altitude. Since latitude 

 39° in the United States is finall}^ passed in the last week in May by 

 the Canadian warbler, it follows that the late spring birds of this spe- 

 cies must make a rapid migration. 



Fall migration. ^T\iQ statements already made outline the probable 

 migration route in fall of the Canadian warbler. The birds from 

 the northeastern section of the United States appear to follow the gen- 

 eral trend of the mountains to the Gulf Coast, being found in the fall 

 apparentlv not east of Mississippi. Thence they cross the Gulf of 

 Mexico to southern Mexico and Guatemala, reaching the Pacific coast 

 at Tehuantepec. They probably then turn southeast and follow the 

 mountains through Costa Rica and Panama to their principal winter 

 home in Ecuador and Peru.
