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 un- 

 known, 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 Mis- 

 souri 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 situa- 

 tions 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. How- 

 ever, 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 fiowering 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 Pennsyl- 

 vania : "The Nashville Warbler appears during the flood tide of the 

 warbler migration in both spring and fall and is sometimes inordi- 

 nately abundant. * * * 



Almost every spring there is a day or two of decided movement, 

 when the species is very common and on occasion exceedingly abun-
