Over much of the southern part of the United States the magnolia warbler, though rare in spring, is common in fall. * * * The general path of migration of the species seems to cross the middle of the Gulf of Mexico. It is bounded approximately on the east by a line drawn from the north central part of Georgia to eastern Yucatan, while few individuals seem to proceed farther west than the coast line from eastern Texas to southern Vera Cruz. In common with some twenty other species of birds the magnolia warbler seems to make its flight between the United States and Yucatan without taking advantage of the peninsula of Florida or using Cuba as a stopping place. At the southern end of the Allegheny Mountains it is a common migrant, while it has been noted only three times in Florida and only once in Cuba. _Winter._--Dr. Alexander F. Skutch contributes the following from Costa Rica: "The magnolia warbler is one of the abundant winter visitants of northern Central America. Although its known winter range extends to Panamá, it only rarely migrates so far south. I have never seen the bird either in Panamá or Costa Rica; nor did Carriker have any record of it when he prepared his list of the birds of the latter country. But in the Caribbean lowlands of Honduras and Guatemala, it is common and widespread from October to April, sharing with the yellow warbler the distinction of being the member of the family most often seen during this period. While it appears to be present in somewhat smaller numbers than in the Caribbean region, it is still far from rare on the Pacific side of Guatemala. Here I found it fairly abundant, during the winter months, on the great coffee plantations between 2,000 and 4,000 feet above sea-level. It was not uncommon in the bushy growth about the shores of Lake Atitlán (4,900 feet), at the end of October; and I even found a few among the pines and oaks at Huehuetenango, at an altitude of 6,600 feet in the western highlands, on November 12, 1934; but I am not at all certain whether they remained so high during the cooler months that followed. In its winter home, this sprightly bird lives singly rather than in flocks. It frequents open groves, light second-growth woodland, thickets, and the riverside vegetation, rather than the heavy forest. "The magnolia warblers arrive in Guatemala and Honduras in their dull winter dress, at the end of September or in October. By early April, the males are in full nuptial attire, so bright and gay that their approaching departure will deprive the region of one of its most beautiful birds. They linger until the end of April; and I have seen males as late as females. "Early dates of fall arrival in Central America are: Guatemala--passim (Griscom), October 12; Colomba, September 30, 1934; Finca Helvetia, October 6, 1934. Honduras--Tela, October 6, 1930.
