return. The Barn Swallow reappears with great regularity in south- 

 ern Louisiana during the first week of August, frequently on the 3d 

 or 4th. By this time migrants have become decidedly numerous 

 and very active. The Louisiana Water-thrush, a species that does 

 not breed in the low coastal regions of Louisiana and Mississippi, 

 appears fully this early. Redstarts grow common. A little later, 

 as a rule, the Worm-eating Warbler, whose breeding range in Lou- 

 isiana corresponds closely with that of the Louisiana Water-thrush, 

 begins to arrive at the coast. Species with much more northern 

 breeding ranges may also reach the Gulf Coast district before the 

 middle of August. And yet the month from July 15 to August 15 is 

 the most depressing of the heated term. After the 15th of August, 

 day winds from the north are not uncommon, and a decidedly 

 autumnal aspect in the weather is not infrequent during the next 

 ten days. Kingbirds now appear in those sections of Louisiana 

 where they are uncommon as nesters, and, in fact, become very 

 much more abundant in all sections. Barn Swallows are even more 

 plentiful than earlier in the month. Orchard Orioles, which are 

 hardly common after August 1, now decrease very rapidly; Gnat- 

 catchers are likewise rather scarce; in the pine districts the 

 Chuck-will's-widow, and the Fork-tailed and Mississippi Kites 

 disappear almost entirely. The last week in August is character- 

 ized by heavy rain storms and distinctly autumnal weather follow- 

 ing. The first transient Maryland Yellow-throats now appear, 

 while the full tide of Yellow Warbler travel is past. It is not 

 unusual to find the first Traill's or Least Flycatchers, and transient 

 Wood Pewees are leaving in considerable numbers. By this time 

 or earlier, the first Bobolinks and Soras are found in the marshes 

 of the southern part of the State, where Black Terns and con- 

 tinually increasing flocks of Limicolfe are assembling. Water- 

 thrushes of both species are now very common. The transient 

 movement of Summer Tanagers begins now, or even somewhat 

 earlier. 



While migratory movements are almost continuous from this 

 time on, it is nearly the middle of September before any fresh 

 arrivals are recorded in. southeast Louisiana. The 15th of the 

 month, however, is signalized by weather that is autumnal in 

 almost every particular, and the full course of the fall migration 

 is immediately under way. Characteristic arrivals are the Mag-
