Forbush (1929) found it "more common in eastern Massachusetts in the latter quarter of the last century than it is today." And my own experience has been similar; prior to 1900 we used to consider the Nashville Warbler a common bird on migrations and even found it breeding in Bristol County in 1892; but we have seen very little of it since the turn of the century. _Spring._--From its winter home in Mexico and Central America, the eastern Nashville warbler seems to migrate mainly northeastward through Texas to the lower Mississippi Valley and then west of the Alleghenies to New England and northward up the central valleys. Some individuals apparently fly straight across the Gulf of Mexico, but it is very rare in Louisiana, for which Dr. Oberholser (1938) gives only three records. It seems to be very rare, or entirely unknown, in any of the southeastern States, east of Louisiana and south of Virginia, except in some of the mountains. According to Dr. Chapman's (1907) tables, about 18 days elapse between the average date of the first arrival of the species in Missouri and that of its first appearance in Minnesota, and it seems to require exactly the same time to migrate from West Virginia to New Brunswick. Dr. Dayton Stoner (1932) says of its migration through the Oneida Lake region, N. Y.: The Nashville warbler here seems to prefer coppices along the edges of woodland such as young aspen and maple and elm thickets and other small growth that springs up in cut-over and burned-over areas. In such situations I have found it singing persistently in late May and the first few days in June. This warbler and the chestnut-sided are often found together. However, it does not confine its activities to thickets, for it not infrequently visits woodlands of tall elm, maple, beech and other deciduous trees, as well as mixed forest and the vegetation in door-yards. The flowering currant is in full bloom at the time this bird reaches the height of its abundance and I have seen it visiting such shrubbery during the first part of May. In Massachusetts in May, according to Forbush (1929), "among its favorite haunts are the bushy edges of woodlands, whether along roads, railroads or streams, or about ponds, lakes, marshes, swamps or open fields. It may often be found among willows, alders, birches or poplars. Old neglected fields and pastures, with scattered growths of birches and bushes, are favorite feeding grounds, but the bird also visits orchards, gardens and shade trees, even in city parks. It may be found on dry lands where scattered pitch pines grow, and on moist lands with rank shrubbery." W. E. Clyde Todd (1940) says of the migration in western Pennsylvania: "The Nashville Warbler appears during the flood tide of the warbler migration in both spring and fall and is sometimes inordinately abundant. * * *
