smilax, dogwood (C. stricta), and several vines, especially Tecoma, 

 Rhus, Cisstis and, of course, Rubus (villosiis). Such growths com- 

 monly occupy the lowest and wettest parts of the delta region, and 

 often border heavy cypress swamps. The Yellow-billed Cuckoo, 

 Cardinal, White-eyed Vireo, and Prothonotary and Hooded War- 

 blers are almost distinctive in this type of country. Of some- 

 what less certain occurrence are the Southern Hairy, Downy, 

 and Red-bellied Woodpeckers, Crested Flycatcher, Red-eyed Vireo, 

 Parula, Sycamore, and Kentucky Warblers, Florida Yellow-throat, 

 Carolina Wren, Tufted Titmouse, Carolina Chickadee, and Blue- 

 gray Gnatcatcher. There is, of course, more or less local varia- 

 tion to be considered in this connection. 



Occasionally an undergrowth of dogwood, haw, deciduous 

 holly, and possibly one or two rarer shrubby growths occurs in 

 heavy w r oods of the prevailing character. Here, again, the Hooded 

 Warbler is plentiful, and frequently the Kentucky Warbler. If 

 a growth of switch cane (Arundinaria tecta) is also present, it 

 proves very attractive to both these species, and seems to supply 

 an indispensable condition for the presence of Swainson's Warbler, 

 which, however, is seldom found even where the switch cane 

 occurs. W T here the distinctive woodland has these undergrowths, 

 the Wood Thrush is most apt to occur as a breeder. 



The summer bird-life of the delta region presents several further 

 aspects as seen in the cypress swamps, in the marshes of the 

 immediate coast district, and in the midst of cultivation and about 

 the edges of the swamps and woods. Although the cypress occurs 

 in practically all situations throughout the section under considera- 

 tion, heavy swamps of this tree occupy rather restricted areas. 

 Their interest from an ornithological point of view is small. Their 

 principal nesting inhabitants are the Woodpeckers, the Green- 

 crested Flycatcher, and the Prothonotary, Parula, Sycamore, and 

 Hooded Warblers, of which the Sycamore and Prothonotary 

 Warblers are the most conspicuous. 



The marshes of southeastern Louisiana present no especial 

 peculiarity. Red-winged Blackbirds and Boat-tailed Grackles 

 are abundant in nearly all situations. The Florida Yellow-throat 

 is uniformly distributed; the Long-billed Marsh Wren and Louisi- 

 ana Seaside Sparrow are somewhat local in their occurrence. In
