The lowlaiul region, between tlie Mississippi and the 

 Oiiacliitii, is alluvial, and tlicrefbre of ie(;ent origin. It is the 

 product of these two rivers as well as the Arkansas, and par- 

 tially subject to inundation. Heavy cypress swamps along- 

 the numerous water-courses alternate with liummock lands, 

 in both of which the majority of hind birds iind abodes, either 

 temporarily or permanently. In the immediate vicinity of the 

 banks ofthe Mlssissii)pi, however, quite a number of species of 

 waders aiul swiuimers, and among them even Terns, etc., idso 

 si»end a large part of the year breeding and rearing their 

 young. This i)art ofthe state, therefore, somewhat resembles 

 in bird-life the coast line of the southern section. 



Western, or rather north-western Lcmisiana, between the 

 Ouachita river and Texas boundary, contains some of the 

 highest parts of the state; the vegetation consisting of both 

 piue and hard-wood timber, the former, however, predomi- 

 nating. The highland is, however, iu some parishes greatly 

 broken up by numerous h\rge lakes, which drain into Eed 

 river. This applies especially to Caddo, Bossier, Bienville 

 and De Soto parishes. In many respects the avifauna here 

 correspcuids to that of the Floiida parishes, augmented, of 

 course, by moi'e western forms. 



The so-called l^Iorida parishes, which now remain to be 

 considered, constitute the entire section ofthe state between 

 the.'iOth and 31.st degrees north, and between the Mississippi 

 and Pearl rivers, east and west, respectively. The topography 

 of these parishes combines the physical aspects ofthe rest of 

 the state already considered, with the exception of the i)rairie 

 lands, and, possibly, the salt-water marshes, for the latter are 

 only represented in a moditi(Ml degree along the borders of 

 lakes Maurepas, Pontchartrain and Borgne. Along the 

 courses of streams only alluvial lands with heavy cyi)ress and 

 other timber exist, while nearly all the rest is taken up, either 

 by pine-tlats or ])ine hills, the latter extending in a north- 

 easterly diiection; the foiiiier occupying the central and 

 southern i)arishes. 



The highlands oi' north-western liouisiana are represented 

 in East Feliciana alone, and this peculiarity has also been 

 recognize<l by a few species of birds, which have nuide this 

 l)arish their bree<ling place in tlie state, eastof the Mississippi 

 river. 



The result of t ids \aried tojiography ot the i'1(»iida par- 

 ishes is: that with the exception of a comparatively small
