88 NORTH AMEEICAK WARBLERS. 



home. The northernmost point from which it haa been recorded in 

 winter is Linares, Nuevo Leon (about 2,000 feet altitude). Thence it 

 ranges through the lower districts of Puebla, Vera Cruz, and Chiapas, 

 and eastward to Campeche and Yucatan. The center of abundance 

 during the winter seems to be from the islands off the east coast of 

 Yucatan through northern Guatemala and the southern half of Vera 

 Cruz. The bird passes south in small numbers to the Pacific coast in 

 southern Oaxaca, and to the mountains along the Pacific side in Guate- 

 mala. In Vera Cruz it is abundant from 400 to 2,800 feet and is less 

 common to 3,800 feet. During migration it passes higher and has 

 been taken at 6,000 feet in Chiapas and up to 8,000 feet in Hidalgo. 

 There seems to be no record as yet of its occurrence in Honduras, and 

 but one for Nicaragua." In Costa Rica it is not common, but has been 

 taken in several places in the mountains from 1,400 to 4,000 feet. 

 Judging from the records it occurs less commonly in Panama than in 

 Costa Rica, but it has been taken both in the lowlands of the Atlantic 

 slope and on the mountains of the Pacific. 



A few scattering records show that the black-throated green war- 

 bler is evidently but an accidental visitant in the West Indies, where 

 its occurrence has been recorded in Cuba,* Isle of Pines," Jamaica,'' 

 Watlings Island,* Dominica,-'' and Guadeloupe.^ The species is com- 

 monly called a winter resident of Cuba, but is never said to winter in 

 Florida; yet the records of its occurrence in winter in the two places 

 are of a similar sort. Gundlach saw a single bird in January, 1854, 

 in western Cuba, and Atkins saw one in January, 1888, at Key West. 



Spring migration. — The earliest recorded date of arrival of the 

 black-throated green warbler in the eastern part of the United States 

 is March 23, 1885, on which date the bird was noted at Pensacola, Fla. 

 The spring records of the species in southern Florida are very few, 

 consisting of one at Tarpon Springs, April 1, 1888, and one at 

 Tortugas, April 26, 1890. In northwestern Florida, on the contrary, 

 on the direct line from the Alleghenies to Yucatan, the bird is quite 

 common in spring. 



In 1885 the earliest date of arrival in Chester County, S. C. , recorded 

 by Loomis was March 31, while the first birds seen at Rising Fawn, 

 Ga., and Raleigh, N. C, Were noted on April 1. The average of 

 earliest spring arrivals for six years at Raleigh is March 30, obtained 

 from the following very even record of first appearances: April 1,
