24 NORTH AMERICAN WARBLERS. 



been noted a few times at San Jose (3,500 feet)," and is not uncommpn 

 in the hottest part of the country of Punta Arenas on the west coast. 

 In Panama it has been taken near Chiriqui October 16 and December 

 10, 1900,' in Veragua, and along the line of the railway. The abun- 

 dance of the species in winter in Colombia is attested by the fact that 

 fifty-eight specimens, all taken in the lowlands along the north coast. 

 Were sent to the United States by two collecting parties." A speci- 

 men has been secured on the island of Trinidad,*^ one at Santa Marta, 

 Colombia,'' one at Valle Dupar, Colombia,-^ one in Antioquia, Colom- 

 bia,'' and one south of Merida, Venezuela.'' These last two records 

 show that some individuals go 'into the mountains in winter; for 

 although the specimen from Antioquia has no localitj' marked, the 

 itinerary of the party makes it probable that it was taken at about 4,000 

 feet, while Merida is at an altitude of 5,400 feet. 



It is thus seen that though most prothonotarj'^ warblers winter in 

 the same character of countrj- that furnishes the breeding grounds, 

 yet wanderers penetrate to higher altitudes in winter than in summer. 

 The northern limit of the winter range is not definitely settled. Sev- 

 eral individuals have been seen in Campeche, Mexico, during the 

 winter,' and the species has been taken in January on Cozumel 

 Island off the coast of Yucatan,'' but it is probable that few winter regu- 

 larly north of Nicaragua. 



Spring migration. — There are few records of spring arrival or 

 departure of the prothonotary warbler south of the United States. 

 The species was once seen in Cuba in April; Schott took one at 

 Merida, Yucatan, March 28, 1865;* and the parties of the Biological 

 Survey saw a few on Cozumel Island April 4-18, 1901. The latest 

 date at which any have been taken in Colombia is January 30. The 

 northward movement undoubtedly begins Barly, for the first prothono- 

 tary warblers reach the United States liy the middle of March. They 

 appear simultaneously off the coast of Louisiana and at the south end 

 of Florida. The earliest arrival noted in Florida was that of a bird 

 that struck Sombrero Key lighthouse March 11, 1888. There is no
