74 BIRDS OF ARKANSAS. 



Migrants from the south reach Helena about the first week of April 

 (earliest, March 24) and the return movement takes place during 

 September and early October. The species was noted during the 

 summer months at Mammoth Spring, Lake City, Conway, McGehee, 

 Eldorado, Delight, Rich Mountain, and Pettigrew. Like the other 

 vireos the yellowthroat is mainly insectivorous, and its food includes 

 a variety of caterpillars, moths, beetles, etc., as well as house flies and 

 mosquitoes. 



Blue-headed Vireo. Lanivireo solitarius. 



The solitary or blue-headed vireo occurs as a migrant in the Mis- 

 sissippi Valley, breeding from Minnesota northward. It should 

 be found regularly in Arkansas in the latter half of April and again 

 in September and October. The only record for the State, however, 

 is furnished by Savage, who saw 2 birds at Delight on October 22. 



White-eyed Vireo. Vireo griseus. 



The white-eyed vireo is almost as common as the red-eye and, 

 like it, is generally distributed. It occurs in both the mountains 

 and the lowlands, and is especially abundant in wet river bottom 

 timber where thickets and tangles of briers cover the ground. It 

 arrives at Helena usually about the first of April (earliest, March 

 23) and remains until the middle of October (latest, October 16). 

 It is reported as breeding at Clinton, Pea Ridge, Newport, Helena, 

 Big Lake, and Delight. I observed it at Rich Mountain, Pettigrew, 

 Conway, Mammoth Spring, and Turrell. 



Bell Vireo. Vireo belli. 



This is the rarest of the vireos and of very local distribution in 

 Arkansas. It is most numerous in prairie regions and occurs also 

 to some extent in rolling foothill country. I found this species 

 rather common on the Grand Prairie about Stuttgart May 11-14, 

 living hi the copses and hedges and even in dooryards close to town. 

 At Conway in June it was fairly common, and at Fort Smith several 

 breeding pairs were located in a peach orchard near town. One 

 was seen at Gurdon May 20. 



Black-and-white Warbler. Mniotilta varia. 



The black-and-white "creeper" occurs as a summer resident over 

 the greater part of the State, but is rare or absent from the extreme 

 southern part. It arrives at Helena from the south about the first 

 of April (earliest, March 20) and remains until October. It has been 

 reported as a breeder at Clinton, Newport, Hopefield, and Helena. 

 I found it at Mammoth Spring, Turrell, Conway, Delight, Rich Moun- 

 tain, and Pettigrew. At most of these localities it probably breeds,
