Griimell Water-thrusli. Seiurus noveboracensis notabilis. 

 This subspecies, the western form of the water-thrush, is a common 

 migrant through the Mississippi Valley and breeds from northern 

 Minnesota northward to Alaska. It is, of course, not a thrush at all, 

 in spite of its name, but a ground warbler related to the ovenbird. 

 It frequents swamps and creek and. river bottoms. I noted several 

 birds of the species at Turrell May 7, and this seems to be the only 

 record from the State. The bird is probably of regular occurrence, 

 however, and may be looked for between April 20 and May 15 and 

 again from the last of August till October. 



Louisiana Water-thrush. Seiurus motadlla. 



The Louisiana or large-billed water-thrush is a southern breeding 

 species, finding its northern limit in southern Nebraska and Minne- 

 sota. It is a fairly common summer resident in Arkansas, arriving 

 from the south about the middle of March and departing in October. 

 It frequents wooded ravines in the hills and, to some extent, wet 

 river-bottom timber. It is reported as breeding at Chnton, Newport) 

 and Helena. I found it rather common in summer at Mammoth 

 Spring, and noted a few at Pettigrew, Chester, and Cotter. At 

 Womble a nest just completed was found May 22, and at Camden 

 I collected a fuU-plumaged young bird July 6. 



Kentucky Warbler. Oporomisformosvs. 



This warbler is a common and generally distributed summer resi- 

 dent in the wooded parts of the State. It is a lover of damp, river- 

 bottom woods, but is found also in ravines and along streams well up 

 on the mountains. It is reported as a breeder at Clinton, Newport, 

 Helena, and Delight. I found it at Pettigrew, Kich Mountain, 

 Camden, Wilmot, and Turrell. The first migrants of this species 

 were seen at Delight April 10, and at Helena April 13 (average date 

 of arrival at Helena, April 20). In the fall it was last noted at 

 DeHght on September 4, but is seen only occasionally after the middle 



of August. 



[Connecticut Warbler. Oporomis agilis. 



The Connecticut warbler is a rather common migrant in spring in the Mississippi 

 Valley, and breeds in Michigan, Minnesota, and Manitoba. Itsfall migration is mainly 

 east of the AUeghenies, and the bird is rare in the Mississippi Valley. It should occur 

 regularly in Arkansas during the first half of May.] 



Mourning Warbler. Oporomis Philadelphia. 



The mourning warbler, so named from the black hood it wears, is a 

 regular and not uncommon migrant in the Mississippi Valley, breeding 

 from central Minnesota northward. Its spring migration is performed 

 during May and its fall migration in September. It has been observed 

 but once in Arkansas— at Helena, May 2, 1909, by Mrs. Stephenson.
