190 Kopman, Birds of Louisiana. [ April 



especially in moist localities. Earliest arrival, April 5, 1902, Bay St. Louis, 

 Miss. Usually commonest about April 15. Latest date in spring, May 

 9, 1903, Lobdell, La. Earliest arrival in fall, August 28, 1899, Bay St. 

 Louis, Miss. Latest departure, October 19, 1897, Ariel, Miss. 



288. Water-Thrush (Seiurus noveboracensis noveboracensis) . In south- 

 eastern Louisiana, except in the pine woods, this species greatly out- 

 numbers the following, which, in fact, is rather rare in the fertile alluvial 

 section. In the pine woods the two species are about equally common in 

 migration, the present species preferring the occasional sloughs and swampy 

 strips among the pines, the Louisiana Water-Thrush frequenting sandy 

 ravines and creek and small river banks, and on the Mississippi coast 

 occurring even on the sandy shore. The Water-Thrush reaches Gulf coast 

 latitude in fall the middle or latter part of August, remaining until Oct. 10 

 or 15 — latest, Oct. 17, 1896, New Orleans. In spring it arrives early 

 in April, but is more apt to be common late in the season. Latest date 

 of departure, May 7, 1897, New Orleans. 



289. Louisiana Water-Thrush (Seiurus motacilla). Those sections 

 of the State where the streams flow over sharp sandy beds are the pre- 

 eminent habitat of this species, both as breeder and transient. As a 

 breeder, it is found chiefly in the northern part of the State, but it reaches 

 the latitude of the coast very early, having been noted at Bay St. Louis, 

 Miss., July 4, 1906, and always commonly after the middle or latter part 

 of July. As previously explained, it is not very common in the southeast- 

 ern part of Louisiana; the earliest date of arrival in spring is March 19, 



1904, at New Orleans. Records of the departure in fall are lacking. 



290. Kentucky Warbler (Oporomis formosus). Common sir 

 visitor in undergrowth of flat, moist woods, such as the better 

 swamps in the lowlands and the bottoms of the more elevated se<" 

 State. Arrives at Gulf coast latitude the last of March : earl : 



1905. Inconspicuous in fall; appears to leave about the p 

 [Connecticut Warbler (Oporomis agilis) . Has d/ 



for Louisiana. I noted either this species or the 

 Biloxi, Miss., on August 27, 1906.] 



291. Mourning Warbler (Oporornis ph. 

 found this bird in the State, but Mr. Andrew A. 

 reasonably sure was a specimen of this species ear^ 

 New Orleans. I have noted either this species or the L 

 at Biloxi, Miss. (August 27, 1906). In any event, it is 

 bird in all sections of both States. 



292. Maryland Yellow-throat (Geothlypis trichas trie. 

 mon winter visitor, all breeding birds being doubtless referable t. 

 form. At the Gulf coast, there is always a decided influx of Yellow- 

 about Sept. 1, but whether this form alone is represented in this n 

 ment, I am unable to say. 



293. Florida Yellow-throat (Geothlypis trichas ignota). An abun- 

 dant resident in all suitable locations.
