Bewick's Wren are more commonly found about the edges of the 

 woods; any moist ground with low cover is freely haunted by 

 Swamp Sparrows in southeastern Louisiana. The Pine Warbler, 

 which never breeds in the delta region, of course, is not common 

 there even in winter. When occurring, it is usually seen about 

 thickets of deciduous trees. 



Before concluding this paper with a consideration of the long- 

 leafed pine flats region in Louisiana and Mississippi, the writer 

 wishes to restate the chief peculiarity of the delta region as being 

 the uniformity of its woodland where undisturbed by agricultural 

 operations, and the lack of variety in its breeding birds. Though 

 the pine flats region presents a naturally more continuous topog- 

 raphy than the delta woodland, which is interrupted by marshes 

 and deep cypress swamps, and though it is less affected by agri- 

 culture, yet within itself it presents a considerably more varied 

 appearance than the woods of the delta region; this is especially 

 true of the pine flats region in southeastern Louisiana; its strictly 

 indigenous avifauna is likewise more varied if less abundant than 

 that in the delta section. The pine flats region, though low, 

 is scarcely level even at its extreme lower border, and rises gradu- 

 ally northward to the long-leaf pine hills region; consequently, 

 it shows two principal growths; (1) the long-leaf and kindred 

 pines, occupying the greater part of the surface; (2) a mixed 

 growth occurring along small streams and in depressions, and 

 composed chiefly of magnolia (especially the 'sweet bay'), red 

 maple, black gum (Nyssa), sweet gum, water oak, holly, wax 

 myrtle, Cyrilla, and a variety of ericaceous shrubs, including 

 Azalea, Clethra, and Vaccinium. In some places, dogwood and a 

 variety of oaks dispute the, higher ground with the pines. Of the 

 resident species of birds found in this region, several are restricted 

 almost entirely to the pines. These are the Red-cockaded Wood- 

 pecker, the Meadowlark, Loggerhead Shrike, Pine Warbler, 

 Brown-headed Nuthatch, and Bluebird. 



The summer visitor species of birds found in this region are 

 attracted chiefly to the mixed growths, and, of course, do not 

 differ very materially from those found in the delta region. The 

 Broad-winged Hawk is common ; the Nighthawk is rather common, 

 and nests in the open pinewoods; the Chuck- will's-widow is com-
